Yesterday, I got stuck installing Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF), November 2006 CTP after my computer had been upgraded to .NET Framework 3.0 Service Pack 1. The installation fails with a warning that a prerequisite, i.e. Microsoft .NET framework 3.0, is missing.
A quick search on the Internet gave me the following trick which works:
- Add the following key and value to the registry aimed at luring the installer:
"DisplayName"="Microsoft .NET Framework 3.0"
- Install vsextwfx.msi.
- Remove the key above.
