If you have an application that uses/needs .NET 1.1 then 2.0 and 3.0 are not
to be considered supersets or replacements for .NET 1.x
So if you where to delete version 1.1 then there is a good chance
the application that requires .NET 1.1 will fail.
Each version of .NET is usually installed along with the application that
requires it, so if you have all three versions, then chances are that
somewhere along the way you installed at a minimum 3 applications,
with each of those 3 applications requiring and installing
it's own version of .NET
The olny other way you could have installed .Net is via the
"Optional Updates" listed when using Windows Update.
