Hi everyone.
Obviously I can't share the code but it can help anyone who is interested.

Remember:
1- antivirus check
2-do not unpack _DEMOPROT.ZIP (it is an update that you will have to use after seeing how the executable works)
3- then you will have to rename _DEMOPROT.ZIP to DEMOPROT.ZIP and launch the executable.

Okay?

I already solved it, creating the ___RESET___.TXT file did not help, I had to delete the keys from HKCU\Software\Security\ as supervisor.

Still the same issue, only deleting the keys from the registry helps, but only for the first run. The next run ends with an error.

After removing the keys from the registry, running the application as Administrator helps. Then the keys in the registry are created correctly. But each user registration requires running the application in As Administrator mode, otherwise it doesn't work. I guess it depends on the Windows security policy settings, mine are quite strict :).
