>On some (very few) systems I receive an error message - "OLE ERROR nnnnnn - class not registered". The classes in question are form classes in my program. Why would I get an error message like that for classes in my program? This happens on only a handful of systems out of hundreds. TIA.
If you use some ActiveX controls in your classes maybe they are not registered on that computer.
