Help problems reinstalling Xara3D6

I had purchased Xara3d6 a few years ago everything worked fine until the other day when my computer crashed. When I tried to download it again from my disc it froze in the middle of installing and it won't let me delete it to install again. When I go to my control panel to uninstall it its not there, but I keep get a pop up stating "Failed to create WebFileUpdater object. Try reinstalling Xara3D6". This happens when I try to install it again. I can't find it to delete it, never had this problem before. Confused need help to install it back in my computer. Thanks..

I thought I posted this earlier but I don't see it.
