ipod software will not uninstall

I had software for an older ipod gen 1 click installed on my windows 7 64bit. I tried to unistall with windows uninstal in control panel. It would not uninstall using the uninstall option in control pane.

Next I tried a product called revo uninstall pro. The process seemed to work until I tried to install itunes and I got an error message that says that itunes could not upgrade the ipod software.

Any help out there for this problem? I need itunes on the pc to sync my iphone and my ipad. And i guess icloud.
