Vista - Can't reinstall Windows Live Suite!

After various problems (which all started with a sound card!) I decided to uninstall and then reinstall Windows Live Suite, but this time with the exception of Live Messenger, which I find both intrusive and a pain! Anyway, I uninstalled it, or so I thought, but when I went to reinstall, it told me that the programs were already on my machine. Since then, I've removed absolutely everything to do with Windows Live that I could find, including some files that I really wanted to keep, but still the same message!

System Restore wouldn't work, and I've tried restoring all my files from my back-up discs, but no joy. I'd really like to get Windows Live back, especially WLM, so can anyone offer any suggestions or assistance?
