Check For Existing Reg Keys?

Hey guys...

I know this may seem basic but it's giving me a hard time...

I have a small installer created, but I need it to do one more thing.

I need it to check for the existance of a reg key, such as HKLM/Software/BLAH, and if BLAH exists I need it to come up with a box saying 'blah was found and installer will be terminated', then the installer would close.

Is that possible?

Getting a 404 error on there.... 🙂

EDIT: I got to it through google cache! Thanks
