How to Update and Play Left 4 Dead 2 - No Steam Edition.

Current Game Version: v2.1.0.0 [March 2012]

Game Details:

Set in the zombie apocalypse, Left 4 Dead 2 (L4D2) is the highly anticipated sequel to the award-winning Left 4 Dead, the #1 co-op game of 2008.

This co-operative action horror FPS takes you and your friends through the cities, swamps and cemeteries of the Deep South, from Savannah to New Orleans across five expansive campaigns.
You'll play as one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. In addition to firearms, you'll also get a chance to take out some aggression on infected with a variety of carnage-creating melee weapons, from chainsaws to axes and even the deadly frying pan.

You'll be putting these weapons to the test against (or playing as in Versus) three horrific and formidable new Special Infected. You'll also encounter five new “uncommon” common infected, including the terrifying Mudmen.

Helping to take L4D's frantic, action-packed gameplay to the next level is AI Director 2.0. This improved Director has the ability to procedurally change the weather you'll fight through and the pathways you'll take, in addition to tailoring the enemy population, effects, and sounds to match your performance. L4D2 promises a satisfying and uniquely challenging experience every time the game is played, custom-fitted to your style of play.

Here's how to play without Steam mucking everything up, and how to update without the need for Steam:

  •   For playing single player via the main menu:
Edit rev.ini with notepad and comment out the ClientDLL line with a # like this:
  • For playing online and enable serverbrowser and SteamGroupServer on main menu:
Edit rev.ini with notepad and confirm the ClientDLL line is not commented out:

possible to reup?
appreciate your work!

Doesn't work. Still crashes to desktop.

Anonymous said...

Thanks a bunch, this was really helpful. My only problem is that the game crashes every couple of minutes without apparent reason. Any fix for that?

Anonymous said...

i keep getting a pop up that says the emu needs to be updated, and yes i've done to reg thing.

Anonymous said...

the links are not working..

satannuts said...


at the "loading..." screen after the intro movie, an error message pops-up-under the game. Just press enter, and wait about 30 seconds and the main menu will load.

Megaupload sucks sometimes - you just have to be patient and wait until the file becomes available again. Maybe their servers are overloaded... lol.

Jason said...

Added the RevLoader and new reg but it still CTD while loading a campaign.

I dowloaded the directplay from ABdcl - no steam.

Any suggestions?

Anonymous said...

is there a way to skip the error message? and what's the command to play campaign mode in lan?

Anonymous said...

To fix the Crash to Desktop it works (at least for me) to type sv_lan 1 into console before playing. Also I always start the game in Adminmode(in Vista, Run as Administrator). Dunno if this has anything to do with it.

Anonymous said...

Does anybody have the qtracker serverlist from before it went down for L4D2?

Anonymous said...

does it work on lan ?

Anonymous said...

hey! Nice one, but please, please can you upload the patch to Megaupload, or Mediafire or something... Rapidshare won't let me download it!!! I want to have patch, because I can't play online :S:S

Anonymous said...

it works perfectly on a lan game coop. however it doesnt let me create a versus game.. i tried creating via console but the only vs map showing is the tutorial map.. which is by the way a crappy map.. can any1 help me with this??

Anonymous said...

We need mirrors! Rapidshare is being an a** at the moment.

Disable Steam Cloud for app 550 & 590 in registry if you CTD at the Loading screen with no error message.

If you have:
Cloud - REG_DWORD - 0x00007fff (32767)
Then Right click CLoud... Modify... Change value data to 0 (hexidecimal)
Cloud - REG_DWORD - 0x00000000 (0)

If you have:
Cloud - REG_DWORD - 0x00000003 (3)
Right click CLoud... Modify... Change value data to 0 (hexidecimal)
Cloud - REG_DWORD - 0x00000000 (0)

any idea on how to play versus game ?

Mo said...


yoann21 said...

The only way i have found to chose versus or another modes is to write in the in game console :
map c1m1_hotel versus (for example)

It doesn't work with
left4dead2.exe -..... +map c1m1_hotel versus

Good job on the guide. Different than mine, but as long as people are getting online, then who cares, right? :)

Does it work with globe's release? It's like 1+ gig. I'll try this.

Thanks. Works great with @globe's release.

Anonymous said...

I haven't tried playing yet. But i did run it and i got to the menu without any problems, when i quit the game there was no error message except for my firewall saying it blocked internet access to the .exe do i want to allow access so i said yes. Ill probably try playing this weekend and see if i get any errors or if it shuts down at anytime. But so far so good. Thanks for the instructions they were easy to fallow.

Anonymous said...

Okay, i couldnt wait till the weekend, so far so good works perfectly. But there were no instructions on how to play online, all that was said is that it works online. So how would i play online. I tried but it didnt work. I dont have steam and i dont even know what steam is for. Could we get instructions on that?

Anonymous said...

So i was playing a little and it works perfectly, but i wanted to try online so i installed steam and i couldnt get online. And now the game wont play at all. When i open it i get steam is not running you must start steam in order to play, even tho i lunched the game from steam. What should i do now? How do i get online?

satannuts, about disabling Steam Cloud, what program is used to change the values and where would i find them?

Why are there no instructions on how to play online? Everything else was easy to fallow but i have no clue what to do if i want to play online.

satannuts said...

dude above me^^,
instruction on how to play? I'll get on that...

The comment about those three failed files... demoheader and drmpe.cfg can be deleted as they are created each time thegame runs. left4dead2.exe probably failed because the exe that comes with the stryder loader is the alternative loader which replaces the original one.

satannuts said...

OK. added info about the serverbrowser. Can't get much easier than that... :)

Anonymous said...

didnt work... uninstall the game then reinstal it with razor 1911 run the rzr.init.exe then delete the paTCH AND THE CRACK FROM ROOT DIRECTORY THEN run the patch then run stryder loader and extract in root again then run inigen and when trying to start the game I get The application failed to start because steam_api.dll was not found... is there something I should do to make it work...?

Anonymous said...

i know you've probably heard this a thousand times already, but i still can't start any maps, right when the loading bar fills it crashes to desktop without any error messages.

Anonymous said...

K so i figured out how to get online from a youtube vid and using garena. I played a little and it works well, using the revloader.exe wouldnt work with left4dead2.exe but w.e as long as it works. Im just wondering tho with the online instructions you put up will i be able to play without steam and garena? Like what will be the difference, will they allow me to get online straight from the left4dead2.exe and actually play will everyone who has a real copy?

Anonymous said...

K i fallowed ur instructions for the server at first steam was off so i couldnt find any servers, but then i turned steam on and restarted the game and now it crashes right when the main menu is about to show, any reason for this? Should i just get rid of steam if i dont need it?

Anonymous said...

I keep getting the error, there are not internet games the fit your filter (even tho i havent done anything to the filter)...? Is there a reason for that, also i deleted steam cuz i just seems to be doing more harm then good and you never mentioned it in the guide so i figured i dont need it.

satannuts said...

@"I get The application failed to start because steam_api.dll was not found," and @"right when the loading bar fills it crashes to desktop without any error messages."

Make sure to apply the FULL update as you may be missing a file or two, also make sure steam is NOT running.
Check taskmanager [ctrl+alt+delete] for running process "left4dead2.exe" and end process if it is running, then try to open the game again. one more thing, is to check your shortcut, and make sure its pointing to the correct directory and exe.

@ the dude posting about Garena and the serverbrowser,
no need for garena, just update game, use Stryder's fix and play on private servers via the serverbrowser.

Charles said...

Hiya and thanks for all the work/help. the game works great on single player, but when i try to connect through serverbrowser i'm get cut off and immediately get this:

BinkOpen( c:\left 4 dead 2\left4dead2\media\l4d2_background03.bik )

huh, it still CTD after all that, ive even reinstalled twice, still quits as the map finishes loading.

Smokey. said...

I kept crashing to desktop after intro trailer and had error 'could not load library file'.

I tried various patches, fixes and loaders and also followed this post AFTER messing with game, to get it working I done the following.

(my O/S is Vista 32bit)

1. Deleted entire c:\program files\left 4 dead 2 folder.

2. Installed Razor 1911 dist.

3. Applied full patch.

4. Downloaded Microsoft Visual C++ 2008 SP1 from link on this page, ran installer and selected Repair (not sure if this actually done anything or not)

5. continued to follow the rest of instructions on this blog.
The instructions on this blog work like magic BUT you might run into problems if you've been messing around with the install beforehand.



Hoth said...

So I'm able to do everything but when I run the stryder patch, I can type in a name (dont think the name really matters), but it wont create the stryder.ini file. Not sure what is causing this problem?????

I'm using windows 7 64bit.......

MasterMe said...

@ Hoth.
You MUST run it as Administrator.
Also, are there some English or EU or US servers?
Those are Russian, and I don't understand a ass of it. :D
Also playing for servers far away gets laggy. :(

How did you get the servers? For me nothing comes up when i look for a game using the consol, not when i go to multiplyer and it searches, it always comes up empty?

Thanks to this new update, no more CTDs! :D

PoLo said...

Hi guys.

Ive got a problem. I downloaded and installed the clean provided here as well as the dec 9 Stryder fix and updated the game to

When launching the Inigen.exe file, I always get an error "Application configuration is incorrect. Reinstalling the app may fix the problem.." Even after I tried reinstalling the Loader Stryder, I still get the same error.

What am I doing wrong?

I also tried launching the left4dead2.exe (hoping it would work), but after the opening CG, the game would close with the error: "Steam is not running. You must start Steam in order to to play this game."

Help is much appreciated. Thanks in advance.

-console -serverbrowser wont apply when i put it in target line

Mohd Farith said...

hey,this maybe an answer to CTD problem. 1st,download and apply for patch at then update your left4dead2 to the latest version(for me i download this website but NOT the full update) n istall stryderloader9(link at above..) and run inigen.exe n put your ingame name.
then in registry turn CLOUD to 0.
hope this will help.thx.

Anonymous said...

what's the different between incremental n full update??? need help for this one.. ;(

Anonymous said...

thanks a lot. I appreciate your work.

satannuts said...

best practice tis to update first then install stryder fix... installing stryder then update will overwrite stryder files...
Make a habit of it. Update then Crack.

difference between full and incremental... ever play battlefield? Full update is like it sounds - it will update ANY version.
Incremental is also how it sounds... one increment at a time.
Best thing to do is just grab the full update if yer updating for the first time.

The CSC folder fix and -lv switch isn't needed for styder fix.

thanks for advice...

Anonymous said...

heyya Satan,

firstly good job at all the stuff u got here. ;)

anyway, i was a late comer to L4D2, so i was still in the middle of downloading the actual game files (installation) so i was up to part 3.

then later i came back to your site and there was some updates done to the downloads.

do i have to re-download from number 1? (this time the filename has the 'clean' attached to it)


Anonymous said...

When I installed clean files then up-to- update along with 12/09 stryder I got steam isn't running error.

So finally I said screw it and installed .0.3 through .0.6 full updates then the stryder. It works now. Hope this post helps someone else who's getting the canned responses that don't work (for them for whatever reason).

I also ran a registry cleaner and deleted all mentions of L4D2 before re-installing each time.

satannuts said...

comments from the last two folks:
the original clean files I had up, had a crack integrated in it.
The revLoader was included, but isn't used anymore as the Stryder fix is now the defacto fix to use.

For anyone experiencing crashes. make sure to delete revloader, rev.ini, steam.dll and steamclient.dll from yer root l4d2 folder only.[where left4dead2.exe is located].

There is a new stryder loader v2.0.2 I think.

Is there any reason why yo switched to REV-EMU?

Add-on support has been added to l4d2 now along with the SDK. Any download link for this?

Thanks man! I have been using your guide for updating l4d2.

satannuts said...

Stryder's Loader did update to 2.0.2.. I might post a package for that, since it requires an un-ReCEG'ed client.dll... i will have to include an un-modified dll with it. It works well.

The Rev-Emu works a little better, and you will notice this as soon as you open the game and see the setti steam group servers on the main menu.. Rev_emu requires the client.dll to be patched with Re-CEG - The latest, repacked updates in this post include a reCEGged client.dll patched to work with rev-emu. I've also heard achievements work with rev-emu and not with stryder, but I have not tested that yet.

So yes. Rev-Emu is the better choice at the moment.

Single player works with updated steamclient, but loads slow like GaNi said. the other option is posted above, which is to use Stryder Loader for Single player and switch back to rev-emu for multiplayer... this should be all cleared up in time...

Its basically Stryder loader with v10 Client.dll. Works like a Charm.

You have problems running the game? Then buy it you retards! It's a great game and a great company that deserves to be supported.

Sharing the offline updates is fine but stealing games is not. Not to mention that when you download something most of the times it has viruses/trojans bundled with it.

Go back and tell your employee you failed yet again and ask them if they would release a game that isn't BETA to the public and expect them to pay through the nose.

I doubt a car company would release a car with 1 wheel and say "we will update in the future until now pay me!"

Buahaha... you ARE a MORON! I wonder if your work is worth what they pay you or if you work for free? Of course not. You are also an arrogant dumbass.

Beta??? You really are an idiot. Every game has some bugs/problems that doesn't mean that they should release them for free. Besides stealing games just make the companies put all kind of crap on them. And as for pirated games... most of them DO have virii bundled with them. And I don't work for any game company. Not everyone is a pathetic thief like you. Get a job you dumb looser.

"We feel sorry for you"??? Who's we??? Every idiot thinks they speak for the rest of the world. But that's what you get when you're uneducated and a looser.

As for cars... have you heard about millions of cars recalled all over the world lately??? I guess not... well? Why we should pay them for "beta" cars?

Think before you post... but I guess that is too much to ask. If you have to steal a game then your life must be really pathetic.

Yes, all those Toyotas with all the problems they have all over the world should be marked as BETA and we shouldn't be paying for them. We should get them for free. That's a great idea. I like it.

Yeah, also doesn't work for me. Windows 7 32bit. I have the clean version you posted + the patch + the latest revemu posted here, and it closes because "Steam is not running." Before this didn't happen.

satannuts said...

yep. the full update includes the original exe and the "rev-emu_fixed2" is missing the fixed exe. So Everyone who used the full update and then the "fixed2", would get "Steam not running".

I've added a new repack [and re-ordered the downloads in the order they need to be installed].

The new repacked rev-emu includes the missing left4dead2.exe that should clear up the "Steam is not running" problems.

I don't understand your question.
You un-check the read-only flag on Msterserver.vdf and then deleted the config folder it was in?

If so, and setti still shows:
check your autoexec.cfg [or server.cfg] if you have these in your cfg folder and look for "setmaster" line if it exists.
delete it.

If its still there, in-game - go to console and use the setmaster commsnd to add/remove/enable/disable master servers.
Usage: setmaster

Type: help setmaster
will show you the above info.

so to remove a master server type:
setmaster remove IP:port
setmaster disable ip:port...

that help you out?

If it doesn't, let me know, there maybe a file or two I can have you delete to set things back to default....

satannuts said...

For those with V-Steam errors = grab the repacked rev-emu and make sure you comment out the following line with a # like so: #ClientDLL=blah blah...

NOte: you can also use the older rev-emu's for v2011: either the fix, or the fixed2... This will allow the "old-faster-loading" and working serverbrowser/steamgroup. BUT You will be using an older rev-emu/game files which might also bring potential bugs/instability.

Best Bet is to use the latest files, and use Qtracker to view/connect to servers until the browser is working again - as it was for l4d1 [history repeats itself]...

Also, any server admins having trouble with crashing at server start, remove sourcemod and metamod temporarily and use the newest ESt/VUP package to fix the server. You will find the server works, but compatiblilty with certain plugins [perhaps even SM or MM] may be causng the crashes... I will be testing this out tonight to see what exactly the problem is.

ood luck, and happy zombie killing!!

I've done all the right steps, update 1st THEN the patch (3 times!)

I get as far as the loading screen at startup before it crashes to desktop, no error is given!

satannuts said...

Check rev.ini and place # in front of ClientDLL=blahblah line.

Make sure to re-download rev-emu as it was recently rpacked.

If you have sourcemod ormetamod installed, temporarily remove them as the 2013 update breaks compatibility.

Duggy! said...


Thanks for the reply!

I have the rev-emu repack, intalled the update and then the patch. The rev.ini file is correct. I don't have sourcemod or metamod installed.

The game still crashes after the intro and dumps an MDMP file!

My game has been killed :P

I used the steamclient.dll file in the latest Rev-Emu pack released about a week ago, and I think it stopped the crashing I was having right after getting to the menu.

I was able to play a game before messing around with it again and breaking it.

The left4dead2.exe they have doesn't work for me and gives me an error about a DLL.

satannuts said...

@Duggy! and @anoymous:

Install the full update 2013, the incremental 2014, then the rev-emu and try to run the game. If it crahes, try rebuilding your sound cache as explained in the " L4D2 Problems and Solutions" post.

If the game still doesn't work after that, then follow the Alternative loading methods at the bottom of this post.
Rename Client.dll.bak to client.dll and use the RevCrew's Modded Exe to start the game.
Note: The default client.dll is fixed to work with the rev-emu for 2013 [and above]. The one with the .bak extension [make sure to enable viewing extensions in windows folder options] is the dll you want to use with the rev-crew's exe that Anonymous linked...

hope everything turns out ok for you two///

Another great update. But could you please split the full update to 200MB parts? Unfortunately I'm on a limited bandwidth and I am not able to download 715MB file.

Thanks in advance.

Irritant4 said...

1. Installed L4D2_Full_Update_2013_The_Passing.exe

2. Installed L4D2_Update_2013_to_2014.exe

3. Installed L4D2_Rev_Emu_for_v2013.exe

4. Deleted sound cache per the Problems Solution post

5. Checked for #ClientDLL=steamclient_l4d2.dll in rev.ini

6. Don't even know what sourcemod or metamod is, so I don't think I have that installed

The game still crashes after the intro and dumps an MDMP file like Duggy's

7. Make sad face at my monitor.

this method works fine for me (full 2013, then 2014, revemu doesn't worked, then installed revcrew's exe)
Just wanted to say that with the revcrews exe you can uncomment ClientDLL=steamclient_l4d2.dll , so you can have the server list in menu screen.

Please update your guide to say the following:

1) install game
2) install 2.0.13 update
3) install 2.0.14 update
4) install addon
5) install addon feb5th
6) install authoring tools
7) install latest revemu
7a) edit name 2x in rev.ini
7b) make .vdf read only
7c) decomment (remove #) next to client
7d) copy over revemu fixed .exe

Pretty much if any of these steps are missed youre stuck with a crashing installation or no multiplayer online gaming.

Lastly, you've been doing a great job but another pro tip is that people can CLONE their installation directory by copy/paste and test future updates/fixes etc without ruining their working install with an old version.

r1dr12aj said...

So I did all of this and the game loads up fine, but I can't play online. openserverbrowser doesn't work, and I don't want to use anything like qtracker, so what can I do?

Duggy! said...

Well, I've done everything:

Reinstalled L4D2
Installed 2013 update
Installed 2014 update
Installed Revemu 2014
Did all necessary checks (rev.ini, .vdf to Read-Only)

Not a thing has changed, still crashing.

Thanks for the help but fuck this game!!

satannuts said...

Are you tring to play singleplayer game or online?
you may need to either comment out or comment the ClientDLL line in rev.ini. - I've updated the guide with info on how to do that in the Install Rev-Emu section.

@Anon who suggested I update the guide.
Done, so enjoy.

Duggy! said...


Well, I'm just trying to get into the game, it crashes at the loading screen after the intro

I've changed the comment on the Client.dll back & forth, no difference.

Rebuilt the soundcache, no difference

I've tried your other suggestions above but still nothing.

My game is fried when I install this update.

r1dr12aj said...

Ok I followed the new guide and I see all the server lists and steam group servers, but I get an error when I try to connect to a game.

It says something along the lines of:

Expecting 2014, got 2007
Expecting 2014, got 2011

Anonymous said...

it works fine for me last time i update to 2011 no crashes. many thanks. now im DLding the passsing.

Anonymous said...


Irritant4 said...

Followed the guide to the letter and getting no change in crashes...just like Duggy's.

commenting or uncommenting ClientDLL=steamclient_l4d2.dll makes no difference. It just keeps making crashdumps.

Works great on globe's release. Only problem I'm having is slower loading screen.

Nice job admin and thank you.

Anonymous said...

Well here's the story:

There seems to be 2 left4dead.exes in the place where I extracted the l4d files: one in the directory before the one named left4dead2 and one in the directory named left4dead2.

I've been playing using the one in the first directory (not the one in the \left4dead2 directory) and its been working fine.

However, I just downloaded the DLC (The Passing) into the \left4dead2 directory and the updates and the rev_emu thing and I try to open the left4dead.exe in the \left4dead2 directory and it tells me it can't find "steam_api.dll".

Does this mean I installed something incorrectly or is there a file missing? Should I try to re-patch and re-update? Because the left4dead2.exe I've been using before (the one before the \left4dead2 directory) is still working fine, but it doesn't have The Passing campaign installed.

Thanks in advance.

OK I haven't installed the 2014 update, but hear me out.

I downloaded the clean 2.0.0 files from the above links, installed the 2013 update, installed rev-emu 2013, did NOT install any add-on support or authoring tools.

Loaded into the main menu fine, used openbrowserserver in console to get the server browser, clicked 'custom', got around 100 or so servers, tried to connect to them... but all returned this error in the console:

"Invalid protocol, expecting 2013, got 2011"

So most of the servers are still using version 2011? How do I connect to such a server?

"The Passing, I wish you were never born."

You are an idiot!

@ satannuts

Works without any problems.

helo there can anyone help me with this error. Can't find background image 'materials/console/background01.vtf'. i just update incremential 2011 to 2013. my 2011 works fine until i try to patch 2013 passing.

Anonymous said...

Thanks for these patches. They are working fine.
Just wondering how non-steam users are going to handle one update per week, now with this mutation system. =D

Anonymous said...

Scratch my previous post - I got L4D2 to at least run now: it turns out I was missing some files and I installed the DLC+patches in the wrong left4dead2 folder.

Anyway, several new problems have come up now.

Although the DLC+patch update worked (I can see the Mutation option and The Passing campaign), when I try to install extra addons (ie. L4D1 survivor skins) it tells me that I don't have add-on support. I'm 100% certain that I got this add-on to work before I did anything with the base files, so I don't know what's wrong here. The version I downloaded was already patched with add-on support, but it might be outdated - I don't know.

Secondly, when I try to run any campaign, the game CTDs (crashes to desktop) halfway when loading. I haven't done anything to the original program except install the DLC+patches and remove a couple of ...odd sound files (they were overriding the original sounds). I've already attempted to solve this problem by disabling DEP, but to no avail. (I'm using Windows 7)

Is there any way to fix these two problems or should I try to re-install it again?

Anonymous said...

Ah, I apologize for all these comments, but I solved the issue with the CTD on loading campaigns. It turns out I didn't have the correct line commented out in rev.ini.

The only remaining problem I have is the inability to use add-ons despite the fact that I clean-installed add-on support from here.

Any ideas?

Could you please split the update into smaller parts 100MB or 200MB?

With the limited bandwidth I am not able to download the entire 750MB file at ones.

Thanks for your work.

@ r1dr12aj:

This issue is because you are trying to connect to a server running a different version to which you ( = 2014)
Actually, just there are a few servers running version

jimmy gibs jr. said...

I have a question:

What is the screen that shows Steam servers on the principal menu of l4d2? It works? because when I click on one of this servers, the game freeze :0
