I am trying to install a new program that requires the .net framework 3.5. I currently have .net framework 1.1 installed on my computer and cannot install any other version (2.0, 3.0 or 3.5). I've tried several times to install one of the other .net framework versions, but have had no success. Can anyone help?

Yes, I uninstalled .net framework 1.1, restarted my computer, then attempted to install .net framework 3.5. I am running Windows XP, service pack 3.

I've tried to install .net framework both ways--direct download and via windows update. Both ways give me an error and will not allow me to complete the .net setup.
