Hi Doug,

I traced through the LoadActiveX method and I see where it looks up the CLSID in HKEY_CLASSES_ROOT. It finds it OK. The problem is that the next thing the loader method does is look at the \InProcServer32 key to get the path and file name for the ocx. In WIN2k, the only key there is REG_SZ with a value of "Microsoft Treeview Control, Version 6.0". I'm not real familiar with the Win2k registry, so I'm not sure what's going on, but it looks like Win2k stores the pathname to the ocx in a different location. Is that correct?

All of this works fine on Win98 and Millennium with the InProcServer32 key present. I am currently loading win2k on a different machine to see if it is a problem with my test machine.

Thanks for your help. Hope to get to talk to you in San Diego.
