--- Comment #25 from Anastasius Focht focht@gmx.net 2010-03-07 13:32:54 --- Hello,
since this affects lots of apps the only way to progress this is having someone providing a full +voicewarmup msi log of .NET 2.0 SP1 installer. Use a clean Windows XP install with .NET 2.0 Framework and enable full msi log before starting the SP1 installer (http://support.microsoft.com/kb/314852).
I already gave some analysis based on Wine MSI output but it's only guesswork until we really get some information how Windows MSI deals with multiple patch transforms containing duplicate keys.
Regards
