I have been having freezing problems with my 12 Ultra upgrade, I wondered if the fact that I installed it over the 11 Ultra upgrade might be the problem. After reading this forum that no previous version is required I happily uninstalled it with Revo Uninstaller, also scanned for leftovers and deleted them. Rebooted and tried to install my 12 Ultra upgrade, 'No previous version found', curses, tried the same with 11 Ultra upgrade, same result, surely I don't have to go way back installing all my previous upgrades so I just restored a disc image I made three days previously and I now have 12 Ultra upgrade working again but with the same freezing problems. Why can't I install my downloaded upgrade without a previous version being installed?
