after talking several times over ICQ nuhi added the .NET Framework under mce compatability with version 1.2, but all earlier versions allow you to remove .NET 1.0
You have to leave .NET 1.0 on the CD!!!!!!!!!!!!!!!!!! If you want to install the UpdateRollup2 you need to install .NET 1.1 SP1 first, but don't remove the .NET Framework 1.0!!!!!!!!!!
try this: set following registry settings: HKCU\Software\Microsoft\Windows\DWM\Composition: 1 (32-bit DWORD) HKCU\Software\Microsoft\Windows\DWM\CompositionPolicy 2 (32-bit DWORD) and type into the command prompt (cmd.exe) net stop uxsms net start uxsms
