--- Comment #1 from Vitaliy Margolen vitaliy@kievinfo.com 2009-04-05 11:55:14 --- Remove your ~/.wine prefix and reinstall your program. You have cd-recording drivers there that won't work with Wine. When reporting bugs DO NOT use winetricks unless explicitly instructed to.
Your problem is this: err:module:import_dll Library FW.dll (which is needed by L"C:\Program Files\Autodesk\Inventor 11\Bin\Inventor.exe") not found
Search for that library inside wineprefix.
