Could not load library client

[Seregalak]

I can't play the game cause this error. Can you help me?

[Skrimm]

nope:P cant help you. Its forbidden:3

[Seregalak]

So, no solution?

[Seregalak]

Every time i check cache, i can enter in the game but i can't play cause of the error "Could't CRC client side dll bin\client.dll.
If i try to enter after this error, i can't enter in the game: this time the error is "Could not load library client".

Validate your files.

[Seregalak]

Validate the file is useless. Doing this thing has the only effect to recreate the file client.dll but this file is erase by the sistem at the first run of Left 4 Dead 2.

Have you try this option? Steam is corruptted

i try but the new error "failed to poke open firewall" appear.
Open firewall port, disable antivirus and run the program as administrator are useless.

Same problem ! Is it solved for you? And how ???

[Seregalak]

I have the problem right now. Still don't get it how to solve it.

[Labusedebase]

I may have found a solution by changing the ntfs rights to the "client.dll" file.
1) Right click on the file properties
2) click on Advanced Security
3) Delete all accounts
4) Add "all users"
5) Deny all rights and OK
6) Change the rights and allow "Read and Execute" OK

I started the game and I can even play. The file is still present. I left steam launched the game again and the file is still present

I have not tested after a reboot but I am hopeful.
I hope it will help

There are a ton of postings about this exact problem. Did you make the effort to search?

[Labusedebase]

Yes i did !

I tried to verify the cache, the file is downloaded again but also deleted when launching the game again.

I tried to uninstall the game by removing local files and reinstalling but the problem persists.

I checked the updates to my graphics drivers

I consulted various forums people seem to encounter the same problem but I have not found a solution.

So I contacted the support that made me remove and install steam

The problem is not solved and because the file is deleted I decided to remove the rights of deleting and modifying. It seems to work

If there is a formal solution thank you's to give !!

[Seregalak]

I'm sorry but i can't do what you said. Can you explaine better?
I think it's my fault but everytime i wrong i need to verify the cache for recreate the file, funny think cause i deny to delete the file ^^

[Labusedebase]

I'm french and maybe that is my English is not very good.
First of all, to save time make a copy of client.dll file. It will save you check the cache every time for it to be downloaded again.

Then follow the steps. I can not put a screen printed so I'll try to explain better

1) Right click on the client.dll file (keep a copy) and click on properties
2) Click on Advanced Security at the bottom of the window
3) Uncheck the box disable inheritance
4) Delete all accounts
5) Add "all users"
6) Check all refused --> OK
7) In the security tab click edit and check "Read and Execute" -->OK

Try !

If the file is deleted again is that you do not do the right thing or that this trick (which works for me I played last night) is not valid for you.

You can copy and rename the copy of client.dll file and try again

[Seregalak]

I try but it's not working. Sigh.
