What I've decided to do is search for errors one "category" at a time, that way the results are not overwhelming and I can eyeball them before I ok them. Some of the errors I'm getting are due to missing files that I will be putting back in, so I don't want them fixed.
It's also just as well I did that, since it found about 100 missing shortcauts, that should have been totally correct and refer to very active programs. For a while I panicked, since all the related directories had disappeard - they are updated very frequently and my backup for them is two weeks old.
It seems that two days ago while moving some files around my finger must have slipped and I moved them all to a different location - anyway that's great since it aerted me to the problem.
I'm also finding lots of old program references to stuff that was installed over two years ago and has long gone.
It also found two missing shared DLL's in Nero, which might explain why I can't write CD"s reliably - it tends to lock up - even though I reinstalled the software a couple of days ago.
