How to determine if an activeX is installed?

[the pink jedi]

how do you check if a particular activeX is installed on the PC? I do not wish to catch InteropServices.COMException or any other exception just to determine if the activeX is installed.

You could look if HKEY_CLASSES_ROOT has a key corresponding to the ActiveX name, or if HKEY_CLASSES_ROOT\CLSID has a key corresponding to the ActiveX guid. EDIT: used CLID instead of CLSID, now corrected.
