------- Additional Comments From elton@schiert.net 2006-20-12 14:32 ------- Hi again. You were indeed right about the regression thing. I found some other apps that can produce the "installation support file"-error with all wine-versions. So this bug has never been fixed.
But I also found out something interesting about the HeroesV-patch: The error is not caused by the patch itself, but by the HeroesV-installer. I think it's like that: When I install HeroesV some bug makes the HeroesV-installer create a file that is somehow "bad". Now when I run the patch-installer it accesses this file, but due to the file being corrupted the patch-installer doesn't know what to do and fails.
The file in question is "C:\Program Files\InstallShield Installation Information{20071984-5EB1-4881-8EDB-082532ACEC6D}\setup.ilg".
I installed HeroesV with wine. Then I installed HeroesV on Windows XP. After that I copied the file setup.ilg from windows to the wine-directory, replacing the existing one, and ... I could install the patch.
