I have a real problem. I have successfully unistalled NAV from 2 of our Computers running XP Home SP2 using Posted info from Mike Flynn. I set out to do the third PC and C Cleaner removed the above file! I tried using the XP CD to repair and ended up with a second install of XP OS. (I think I boobed somewhere). My question is can I uninstall this second OS? I've gone into "msconfig" and BOOT.INI and it shows : multi(o)disk(o)rdisk(o)partition(1)\WINDOWSC= "Microsoft Windows XP Home Edition" /fastdetect under operating systems (highlighted in blue) then another line immediately below shows : multi(o)disk(o)rdisk(o)partition(1)\WINDOWS= "Microsoft Windows XP Home Edition" /fastdetect /tutaq=q5xujl /noexecute=optin. The new install has nothing in the ADD/REMOVE Programs in Control Panel, but if I Right Click on MY COMPUTER>Left Click on Local Disk C: it opens with all the files and programs on the PC originally. How can I sort this out without losing all the info stored on the disk???
