Hi ... ok..
1- Thanks for the link to "take ownership" instructions.. those are the ones I have already been trying to use.. but I STILL can't rename the catroot2 file. I've followed the ownership instructions, and when it didn't work, I rebootedin safe mode and did it again.. each time, the CMD window said I had been successful in taking ownershiop, but when I went back to the system32 folder, it still would not let me rename catroot2. Is this important...I read in one explanation here
You cannot install some updates or programs
that catroot might only be releveant to XP and Win2003 ??:
2- error number ??? Not at all.. no error number. The PC just reaches a point at the end of the SP1 install, where it's rebooting and then says on screen something like "SP1 install failed - reverting changes" and spends the next hour rebooting and undoing all the changes it made.
