Windows Messanger Versions

I had Microsoft Messanger version 4 on my Windows XP Pro
computer. I never used it. However, I decided to try it
out and ended up installing Microsoft Messanger version 5.
I now have both versions installed and I decided I do not
like either. The problem is that I can't figure out how to
get rid of them. They are not listed in the Add/Remove
preograms list on the control panel and there is no
uninstall program in thier folders. What should I do to
get rid of theses programs that are just taking up space?

By the way I am also using IE 6 sp1.

TIA
