>i think Christof is going in the right direction. i you .vcx is not specified in the program, your .exe has to search for it. there are certain rules how vfp does this (i saw this 1 time in the msdn library). if i remember correctly the path setting from windows/dos is included in that search.

Our root EXE includes:

SET CLASSLIB TO FournierTransformationListe ADDITIVE

at the top of the program. So, this is executed and put in memory. It's still a mystery why the other EXE can't see it on one specific server. That object is part of the included files of the root EXE.
