Can't get L4D2 to Start from Steam Client
Do you think this may be due to the fact that I installed the game in a custom directory?

As soon as I click L4D2 I get an (unknown error) and it won't launch. I decided to go straight to where I installed the game and run the exe from the common files and it runs! However I get this message: [IMG]http://i.imgur.com/aSSNVYj.jpg?1[/img]

I've checked the launch options and do not see -insecure there...is that because I am running the game outside of the steam client (with steam still running)? I'm running out of ideas here and at wits end!!!

Thanks for your input! Unfortunately it didn't work. I even unistalled/reinstalled to no avail. Still getting an (unknown error) message when trying to launch from steam. I even installed it in the default drive/directory.

Valve..we're going to have beef soon if I wasted my money!

edit: figured it out. If you're on Windows 8 and having this problem, it could be due to not running steam as an administrator and no turning UAC all the way down does not make every program run as admin like it did in W7. Exit steam, then right click and run steam as admin and it should resolve the problem.

I had this same problem with a fresh install of Steam and L4D2 on a secondary internal hard drive. I found my problem was a permissions issue with one or more folder in my %userprofile% directory (typically c:\users\[username]).

In my case I had to take ownership of ALL the files contained in my user profile directory, then reset all the permissions to inherit from parent.

To take ownership, go to Start -> Run -> "%userprofile%\appdata"
Then for each of the folders, follow these directions (be sure to select the "replace owner on subcontainers" option:

Then I had to reset the permissions of all the child objects. I did this by doing the following for each folder:
Right click -> Properties -> Security tab -> Advanced -> Change Permissions... -> check "Replace all child object permissions..." -> OK

Hopefully this will help!

I had the same problem. Running Steam as Administrator solved it. :)

Fair enough, but I would never consider that a solution, just a temporary workaround.

Unfortunatly, after checking many posts about running Left For Dead 2, i still can't play it.

I have re-installed the game, all steam, deleted everything about steam from my computer, checked Direct X, checked permissions, runned as admin, changed some DLL properties.

It says that the game is going to start, but then in the task window, i notice that the task for Left For Dead ends.... What can i do?
