I was also getting this bug when using Play On Linux.
However, without POL (without a wine prefix), the game ran and passed the install error.
I am not sure if it is Play On Linux or using wine prefixes. L4D2's DRM check or whatever doesn't like it.
1.1.43 Confirmed working with a straight wine (using ~/.wine) install.
Confirmed NOT working when using play on linux, with 1.1.33 - 1.1.43.
Yeah, that was my problem. Now I'm just getting horrible fps...
