I'm also having troubles getting it to run on my gentoo. using a gtx560ti with the latest nvidia drivers for linux 285.05.09 it fails with the error: Failed to create XAudio2 engine which is described on the installation page. so I try: lieven@cthulhu ~ $ ./winetricks xact_jun2010 Executing w_do_call xact_jun2010 xact_jun2010 already installed, skipping lieven@cthulhu ~ $ ./winetricks vcrun2010 Executing w_do_call vcrun2010 vcrun2010 already installed, skipping so no help there. the install was done using an msi-install of steam, not winetricks because it creates a new prefix. my install is in the only ~/.wine prefix. any suggestions? thanks.
