Files missing from Windows registry

[Rabbit]

I have a unknown number of Windows registry errors on my desktop. I fix one, I get another. My question is, is there a safe and effective program I can buy/download that will scan and fix them? I don't want to do a full fresh install on my computer as I have to many important files on it, also if I did, would it delete all the things on my other 2 hard drives?

I have windows 7 64 bit, all the files that are missing are missing from "SysWOW64" in my local drive. I only found them because bf meshview brought them to my attention when I tried to run it.

Umm, I don't think this is a Win7 issue, I think it is a BFmeshview issue.
However if you are sure it's a win7 issue, you can do this:

you can rebuild your SysWow64 directory with your windows 7 installation disc/media/compressed in place upgrade files using this method:
