>Hi,
>Is there a function to check if a VFP DLL is registered?

You can check for existence of its' CLSID in the Registry under HKEY_CLASSES_ROOT\CLSID.
Of course, just CLSID existence does not guarantee that it is properly registered and the rest of necessary keys are in Registry too.

>And is there a alternate way to register a VFP DLL beside regsrv32 and setup routine?

You can manualy (programmatically) create the necessary keys in the Registry (but that would be repeating of what the above mentioned ways do)
Or build the DLL on that PC :)
