|That is because the 'tabctl.ocx' file has not been registered on the target machine. I am assuming you are just copying the exe file from your machine to the other?|
That not really the right way to approach deployment, what you really need to do is, package your application and all neccessary ocx and dll files into a setup file which will register them on installation.
If this is a one off install you can copy the ocx files from the development machine, onto the target machine and register the ocx on there. Check the link below on how to register ocx controls.
