Well, you can use the following logic:
1. Check if all needed ActiveXs are registered.
2. If not, try to register them
3. If success, launch the form

Isn't it the problem I gave you a solution for?

Click on the Book icon in the left panel (this is the Knowledgebase icon), click on "frequently Asked Questions", click on "ActiveX controls in VFP", click on "How to register/unregister an OCX/ActiveX programatically".
