Are there any parameters missing by anychance? What dependencies exist for the dll? Is the version on the dependencies wrong or are they missing entirely? In other words, what operating system dlls does ValidacionClaveSecreta.dll rely on? Also, was the dll registered on the workstation?

We call a dll this way:

DECLARE INTEGER PR_Contract IN PrintEngine STRING, STRING, STRING, STRING, INTEGER, INTEGER

IF ExpContract(hdir+'PROUT.DAT')

	IF PR_Contract(hdir+'PROUT.DAT', sprinter, sbin, 'PRFORM', iMethod, num_copies) = 0

There is plenty of information on the web that you may find helpful to read (the links explain it much better):
