Wednesday, April 04, 2012 4:51 PMI see that I have some Microsoft programs duplicated at different versions installed on my Dell computer. Do I need all of these?
Microsoft.net Framework 1.1
Microsoft.net Framework 2.0 Service Pack 2
Microsoft.net Framework 3.0 Service Pack 2
Microsoft.net Framework 3.5 SP1
They take up quite a bit of my available memory.
I am running XP.

Yes all of them are required.
Multiple version of the .NET Framework provides the run time for execution of the applications that uses .NET Framework run time. It is not recommended to uninstall .NET Framework 2.0 SP2, 3.0SP2 & 3.5 SP1. However if you want you can uninstall .NET 1.1.
Also please donot delete any files from the C:\Windows\Installer\

Whether they are required or not depends on the programs you have installed that need them.
Removing any .NET Framework from your system means you risk losing the use of any program(s) that require that version.
Further, some of the .NET Framework "versions" you list are not full versions and require other versions to be present.
Case in point. .NET Frameworks 3,0 and 3.5 are NOT full frameworks, but extensions of 2.0. That means you CANNOT have 3.5 if you remove 2.0. Think of .NET Framework 2.0/3.0/3.5 as ONE complete framework.
Another thought: Although you could risk removing .NET Framework 1.1 (unrelated to the other versions you have installed), it is very small and removing it will gain you VERY little disc space.
I recommend you leave the installed frameworks alone and investigate safe ways to recover disc space on your XP system here:

I would suggest you to keep all the frameworks and not to uninstall any of them. You can free up disk using lot of tools like CCleaner or using fragmentation or disk cleanup
