I have VB6 installed on 2 separate computers. On the 1st, I created an ActiveX command button and compiled it into an .ocx file. On both computers I have a copy of the same application files. After copying the .ocx file to the second computer and using the new ActiveX control, I modified the application and copied the files back to the 1st computer. When trying to access the application on the 1st computer I receive a "Class Not Registered - Error 713" error. VB won't allow me to open the form on which I used the new ActiveX control. Why doesn't VB recognize this control when it was created on this computer?
