So I got myself a little early Christmas present, but installed it to the wrong hard drive. No bother, I figured, I'll just uninstall and reinstall. Unfortunately our power went splat for a few minutes halfway through, so when I tried to run the uninstaller again, it crashed with some suitably obscure message.

No bother, I figured, so I deleted what was left manually, and went to reinstall. And herein lies my problem. Whenever I start the installer, the first thing it does is ask me if I want to remove the program (???). I say yes, and it crashes with a nice obscure message. I went through my registry and removed any reference to the program I could find, and that got me to the installer launcher at least, but when I click on Install, it goes back to it's trying to uninstall non-existant files problem.

So... Anyone know a good registry cleaner that will clear out any junk I might have missed that might be causing problems, and/or a good utility for getting rid of useless files that might be causing the same problem?
