The .NET Framework version 4 cannot be installed because the .NET Framework version 1.0 is already installed on your computer

I ran into this error message while trying to install the .NET Framework 4.0 Beta. I went into Programs to remove it and it wasn’t listed. Hmmm. So the first thing I did was download this tool:

Run in and it will tell you which versions of the .NET Framework you had installed. Sure enough 1.0 was listed. So a quick google search brought me to this tool that removes versions of the .NET Framework.|_Tools/dotnetfx|_cleanup|


Just a quick note that this comes with no warranty. It worked for me but the cleanup tool is messing with the Registry so do so at your own risk.
