I'm having a problem with the cTreeViewCtrl on a form. Its running on a dozen or so WinXP computers with no problem. I have 3 computers though that refuse to run the form that pop-up the error 1426 "Class not licensed for use". I've reas and reread threads that appear to say using MMortals cTreeView dropped on a form should have the cTreeViewCtrl ready to go.

What am I missing?

Thanks
Jon
