@Michael: The return value doesn't really seem to be consistent, and is different for many Windows versions. See: http://newtestbot.winehq.org/JobDetails.pl?Key=9387
I doubt that the app really relies on that.
@Sebastian: I guess that this link is no longer showing ID 9387. I got an idea to test this installer on real windows, which are not "consistent". Thus we will see, if this is some other kind of wine's insufficiency or the installer _really_ depends on returning the zero.
Do you remember, which Windows version behaved inconsistently?
