I distributed my program to quite a few people ( used the new VS installer. much nicer than P&D Wizard).

Anyway, a number of them get a CLSID error with a bunch of numbers next to it.

Why does this error occur?

I thought that it had something to do with controls not being properly installed, or out of date or something. But i see no way to diagnose the problem, and i'm getting really frustrated!

Can someone please help me?? =(
How do i fix this? (
