>>Tried as admin with no success, but actually it was working without admin rights before 8.1.
OK, it could be a Molebox versioning issue but as per previous, Molebox is ineffectual protection for a VFP app anyway. Have you considered Defox or VFP Compiler? The protected product can be installed by xcopying a handful of files to a folder on the destination machine and they're both far too difficult to hack even for the sorts of C++/VFP guru who can disassemble the ASM or C++ to figure out what is happening.
No matter what protection you use, watch out for use of external encryption dlls. If you rely on one of those, your encryption keys can be hooked from a VFP app the moment you access the dll, without bothering to decompile the rest of the app.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
