Uninstalling WinFX Beta 2 bits....

So I wanted to install WinFX on my Team Foundation Build server to it could build one of my WinFX projects. Ofcourse I first tried to install the version I thought I had on my workstation (WinFX Beta 2). But that didn't seem to work, so I decided to upgrade both my workstation and build server to the latest .NET 3.0 July CTP Release.

Uninstalling on my workstation went smooth, but uninstalling on my build server didn't go so well.

In the uninstall log left by the uninstallation tool it said the following:

If you have a log file similar, try the following:

In a cmd line go to the following folder: "C:\Windows\WinFx\v3.0\Windows Comunication Foundation", then run "ServiceModelReg.exe -ua". This should manually uninstall the stuck services.
