Strange behaviour old install of office 2010 (O14_RTM_VL.1_RTM_EN). Has worked ok for more than a year, activated with MTK 2.4. Suddenly it wont start (some message stating it could not find valid licence). Fresh EZ-activate with MTK 2.6.1, it said activated ok. Still will not start. Thought I should uninstall, and reinstall. Uninstalled with MTK 2.6.1, progress bar flashing forever, no progress. Boot, tried uninstall with Microsoft fixit 50450, it said uninstall finished ok. Boot, then fresh install from same good old trusted CD which I have used in many other cases. Progress bar working to then end, but then it goes back to about half way, and after a while it gives up. ("Microsoft Office pro plus 2010 encountered an error during setup"). Tried Advanced system care with registry fix, did not help. Virus check, nothing. Am stuck, any suggestions ? regards snofte
