I started out with Net Frameork 1,1 and then from there i now have have 2.0 and then 3.0 SP2 ,,,,the latest update was

Net Framework 3.5 SP1.. I want to know if i should uninstall one of these,, I'm sure I would not need them all. Net Framework 1.1 worked fine for me and then through automatic updates,,important updates only I have accumulated these in the add or remove programs, If anyone has a solution to this or has experienced the same thing please respond !!!! I need to know if it is safe to uninstall one of these!!!!!!!!

Thanks!
