I cannot get version 8.0.16 to uninstall from my Laptop. I am trying to uninstall this version and install 8.0.4. It starts the uninstall, opens the InstallShield Wizard, progress bar runs to about 1/2 way then it just disappears and does nothing after that at all. I am running Win7 64bit on this machine. Now I cannot install the new version nor uninstall the old one? Should I try to eliminate it manually by deleting program files and using regedit to clear registry entries?
