I had a problem installing Photoshop and followed the recommendation to run
the windows installer cleanup utility. this has screwed up my entire pc,
corrupted my profile and cost me an entire day to get my pc back into shape.
However, I still have one major problem. Somehow, Windows Installer no longer
works under UAC, which causes all sorts of problems. For instance, every time
I start up an Office 2007 programme, it starts configuring things and then
tells me "Microsoft [Word] is not installed correctly for the current user.
Please run Setup". I've tried for many hours to find a solution for this and
then realised that it all works fine when UAC is turned off. Also, driver
installations which normally happen automatically go into an endless loop now
when UAC is turned on, but all is normal when it is turned off.
My conclusion is that after the installer cleanup utility, somehow the
permissions got messed up for windows installer. I've searched through the
registry but couldn't find anything unusual. Any help would be greatly
