Jens, I'm really sorry for all the mess that I'm causing with this bug report. But I have another unfortunate finding: I'm getting "MSI_OpenDatabaseW unknown flag (nil)" trying to install dotnet35sp1 in wine-4.0.2
When I made the bug report, the installer of Office 2007 SP3 was triggering the issue. When I saw that dotnet35sp1 was affected to, I changed the focus to this installer. At that time, the Office SP3 was installed successfully in wine-4.0.2 (Debian). I didn't tested dotnet35sp1. I"ll try to explain this and summarize all the facts in upstream report.
