Thanks for the help! I still am getting the following message: wine: cannot find L"C:\\windows\\Microsoft.NET\\Framework\\v2.0.50727\\mscorsvw.exe" I am using wine 1.2 installed through the ubuntu ppa. I am using 64 bit ubuntu so my lib directory is /usr/lib32/wine though I don't know if that makes much difference. Also my full path for the v2 .NET folder is: ~/.wine/drive_c/windows/Microsoft.NET/Framework/v2.0.50727 Not sure if it makes any difference since you didn't have the windows folder between drive_c and Microsoft.NET. The error message I'm getting is pointing to my directory anyway. Really not sure why it isn't seeing the file though. > > $ cd ~/.wine/drive_c/Microsoft.NET/Framework/v2.0.50727/ > $ cp ngen.exe mscorsvw.exe > $ cd /usr/lib/wine > $ cp ngen.exe.so mscorsvw.exe.so >
