Hi Randy.

"2C247F23-8591-11D1-B16A-00C0F0283628 is not properly registered on this machine" when trying to open a form with a ctreeview control.

cTreeView is actually based on my SFActiveX class to handle runtime instantiation of ActiveX controls. Have you traced the code that instantiates the controls (the LoadActiveX method in SFActiveX; I don't know the method name in cTreeView). It'll likely point you to what's going wrong.
