.NET

Over the years various versions of .NET have been deployed to my client machines via WSUS. Now it seems that on many machines these installations have hosed eachother, and certain .NET security updates are failing.

I verified that I can run the .NET cleanup tool to get rid of all the .NET installations on a client, and I can then push out .NET 3.5 via WSUS. This seems to have solved the problems I'm having on the machine I tried it on.

So the question is: if I've got .NET 3.5, is there any reason to also have previous versions installed?
