Make sure that there version match and you don't have other copies in different directory in the Windows search path on that PC.

Sergey,

Thanks for the reference. In order to get rid of the first problem (Class is not valid) I got rid of even baseform class and created both forms from pure VFP classes, just to finish with the simple project.

I also found lots of Vfp* files (170) in different places on the c drive. For now I copied the bare minimum of dlls into my project directory and was able to run the exe from Windows Explorer.

In the long run I will have to examine this problem in depth...

BTW, how do I find if the versions match? By the timestamp?
