Hi Mel,

>I noticed that Net 1, 2, 3, and I think 3.5 ended up being installed to run different programs that required different versions of NET (which seems redundant to me). I can just see in another few years no telling how many more versions there will be.

In theory it should be sufficient to install the latest version only. .NET application will by default switch to the latest one if they can't find the version they are looking for. Unfortunately, some application heavily relied on undocumented behavior in these older runtimes and don't run in a new version.
