Kept getting error 2 see earlier post. Uninstalled PE 9.0 A lot of Acronis registry keys left that give Error when you try to delete them. Tried in Safe Mode Tried with regedit.exe and regedt32.exe both give Error unable to delete key, I'm in XP Administrator mode. Properties for these keys show I have access. Why can't these keys be deleted? You expect uninstall to actually uninstall. Are there instructions for complete uninstall of PE 9.0 (short of a reformat and reinstall of XP)?
