It's a bit depressing that Andrew isn't around here much to help us with the fundamental problems we're having with Kb.

Solve a few of these and it would be an excellent program.
Almost invariably Windows requires some kind of administrator account privileges to install programs. For security's sake it does make sense, but it makes things harder. It means, for instance, that I have to install every new program that comes along on my wife's machine, because I've declared her unsafe to have the admin password.

So to get Kb into C:\Program Files your account has to be able to write into that folder tree. In your circumstances that my not be possible. You could try installing Kb into, say, C:\Users\j97\Downloads\Keybreeze - a data area - where you certainly have write rights. And then run the program from there. Odd, but it may work.
The big problem is that Kb may demand Admin rights just to run, and we're back to square one. I haven't yet tried what I'm suggesting.
