--- Comment #3 from Anastasius Focht focht@gmx.net --- Hello Austin,
it might be interesting to get a verbose MSI log (+voicewarmup -> http://support.microsoft.com/kb/314852) from your Windows machine for the .NET Framework 2.0 SP2 install part. Starting at the point where .NET Framework 2.0 SP1 got installed and the install blocker key (SBS) is present and set to '1'.
You might need to redo previous steps or restore to some earlier snapshot. I don't know if your Windows install can be rolled back without any trace of SP2 (files and registry).
Maybe it's some client-side vs. server-side MSI install thing again.
Regards
