Does not hurt to register an existing OCX. They usually are found in the WinSys folder if you want to check for their existence first. If you want to check if they are registered, you first need to register them on your computer, then check the registery to see where they are. Then check the value of those keys on client PCs using your VFP PRG. If these keys or string values are missing, then register the OCX. Don't try adding the registry entries yourself because you will most likely miss something.

>Just one last thing. Is there a formal way of checking for the existence of a DLL/OCX rather than checking for the file(s)? or is it Ok to just do a REGSVR32 over and over without checking for it's existence?

>>It depends on the actual error message. The most common is invalid license. This basically means you have a developer license installed on your PC but not on the end-users. This is usually caused by programmaticaly adding the control to a container object. The work around is to subclass the control by dropping it onto a form. Then you instanciate that subclass and work from there.
