--- Comment #7 from sl@shback winecreations@trashmail.net 2009-10-04 15:37:24 --- Nope, please let this bug open. I just retried with command "wine dotnet20.exe" and the installer now tells it has "sucessfully" completed, but certainly RegSvcs.exe crashed again before.
Attached a new output of console.
