1. If you have a previous version installed, remove it completely from your system and reboot.
2. Install new version, choose free during installation. You can customize your settings.
3. Do not launch the program after installation, untick auto launch option and close it.
4. Copy and replace cracked file in app directory.
5. Use a firewall and block the program for both incoming and outgoing connections.

Note: Same logic with portable version also. Unpack anywhere you want, drag the fixed exe into portable folder.
