1. Run as Admin "BlockerKeyVerificator.cmd"
2. Install the trial version but not launch it. Make sure to close the program properly (close from the taskbar icon).

If the program wants to be updated, it will be put in the version without a registrar. Just download the latest version and patch again.
VERY IMPORTANT! Do not run the trial license.
If you installed and activated the trial days do not forget to delete the file "CcLeaner.dat"
