"Doesn't work"

I'll update the guide to account for one common Vista problem, which depends on your own PC-settings btw, so I and others won't have to explain this for the next n-times someone asks about it. In the meantime I suggest you verify two things:

1) You are admin of your PC
2) The UAC is turned off.

And of course, any error-messages etc. etc. would be very helpful.
