As a Caveat to my previous post, permit me to quote from this blog post
(from Aaron Stebner's WebLog):

There are a couple of very important caveats that you should read before
using this tool to cleanup .NET Framework bits on your machine:
1. This tool is designed as a last resort for cases where install, uninstall
or repair did not succeed for unusual reasons. It is not intended as a
substitute for the standard uninstall procedure. You should try to perform
an uninstall from Add/Remove Programs before using this cleanup tool.
2.This cleanup tool will delete shared files and registry keys used by other
versions of the .NET Framework. If you run the cleanup tool, you will need
to perform a repair or reinstall for all other versions of the .NET
Framework that are on your computer to get them to work correctly
afterwards.
I have been using this tool for a while, and it has proven reliable, but
there may still be bugs in it in certain scenarios. Please contact me if
you run into any issues while using the cleanup tool or if you are still
unable to install the .NET Framework (or any service packs or hotfixes)
after running it.
