I am trying to uninstall Image Modeler 4.0.2 by both the Remove/add programs and through the Programs-Realviz-image modeler-uninstall Image Modeler with the same result:  an error box stating " An installation support file could not be installed.  The system could not find the specified file."  I then tried to reinstall the original disc, but though it starts the install wizard, it abrubtly stops and states "There is nothing to be done.  Any ideas to uninstall Image Modeler 4.0.2?

Never mind, folks!  I just figured part of it out...I used System Restore to restore it to a point where I had removed it once before.  Maybe when it had been removed and restored before, the uninstaller file got lost somehow.  If I have any more problems, I'll repost.  Thank you all for thinking about it.
