hmm.. regtlb seems to be working on both sides (32&64) but when trying to execute regasm on 64-bit side it fails for example: Code: err:process:start_process L"C:\\windows\\Microsoft.NET\\Framework64\\v2.0.50727\\regasm.exe" doesn't have an entry point, it cannot be executed when running command: Code: wine64 regasm /codebase System.Drawing.dll in folder: ~/.wine/drive_c/windows/Microsoft.NET/Framework64 in 32-bit side of framework the regasm works as expected. So this might be one of the issues why some of the recource dlls cannot be loaded as those must be registered to gac. Do not know if this is correct explanation for the issue, but somehow all the installers fails at the same situation: registering 64-bit assemblies.
