Similar problem here...
Something has gone wrong with Windows Installer...tried several "fixes" but no luck yet.
What I want to do is:
* Take this HD out (while it still "works")
* Put in the new 120 GB HD
* Transfer my XP Pro SP2...and the rest of my software...maybe then do a reinstall which should repair the Windows Installer.
There are no installation discs, but
I have made recovery discs ...2 years ago and again a fresh set near the end of last year.
I have my Acronis back-up...a mirror and a normal back-up.
Dunno where to begin...
If I try to reinstall my OS now, on the existing HD, will I lose all my other progs?
