Which versions of .NET Framework should be on my XP machine?

[Some dumb guy]

After the latest MS Update, in Add/Remove, I see:

2.0 Service Pack 2
3.0 Service Pack 2
3.5 SP1

Should I remove all but the latest or should I add 1.0 and 1.1?

You need all versions of the .Net Frameworks as they are all
"independant" from the other. Microsoft has not made .Net 3.5 to have
every modules from 1.0 to 3.0.

If a software package requires .Net 1.1, it needs 1.1.
