Installation internal errors 2503 and 2502

On Windows XP Pro SP2, when I try to install *anything* I get internal error 2503, click ok to acknowledge, immediately get internal error 2502, click ok, and machine aborts the installation.

I can't find anybody who knows how to fix this problem.

Thanks Laney
