Are all those version in the Program Files folders?
Or are you going by what appears in Add / Remove Programs?

WinXP has a habit of showing older versions of programs in the Add / Remove Programs when they aren't still installed. Cleaning the Windows Registry would be needed to clean things up.

On the Add/Remove Programs window, do you have the Show Updates check box checked off? If you do, uncheck it because it is just showing you what previous versions you had.

Perform a registry scan to delete all bad registries. I suggest using the CCleaner. When programs are uninstalled, they sometimes leave the program registry key behind and removing it may take the program off of the Add/Remove Programs list.
