How do I fix the error that started popping up in a lot of applications:

To run this application, you first must install one of the following version of the .Net Framework: v2.0.50727.

Would you like to download an install version v2.0.50727 of the .NET framework now?

Unfortunately, this is not as simple as just installing the .NET 2.0 runtime, because its already installed. If I run the recommended installers for .NET 2.0 or .NET 3.5 SP1, it exits silently.

Events leading to problem:

Installed SQL Server 2008 R2, which installs a toy version of Visual Studio 2008 that only deals with SQL specific projects.
Uninstalled Visual Studio 2008.
