>The ProgID and VersionIndependent ProgID remain the same. My CLSID for VisualFoxPro.Runtime.6 now reads {008B6021-1F3D-11D1-B0C8-00A0C9055D74}; I'd assume that MS follows its own rules, but they've been known not to do that in the past...any time I change a registered component, I re-register, since it can't hurt.

Well, that's what I *thought* (and hoped), but I've been known to just drags bits for certain products and have it work because the CLSID never changed. Couldn't remember if that was the case with VFP or not.
