Can't uninstall eDrawings 2007 after installing 2008

I have had eDrawings 2007 installed on my computer, but onlyrarely used, for quite a while. In a moment of stupidity, I decidedto upgrade to eDrawings 2008. I assumed, apparently wrongly, thatthe install of eDrawings 2008 would remove eDrawings 2007. Itdidn't and now I have two rarely used programs on my computer.

When I try to uninstall eDrawings 2007, the Windows (XP)uninstaller complains "The feature you are trying to use is on anetwork resource that is unavailable."

Does anybody know a workaround that will allow me to fullyuninstall eDrawings 2007?SolidworksEdrawings
