Evaluate Pro when Licensed for Standard

BC3 logo BC version 3 or later

If you are licensed for Beyond Compare Standard Edition but you want to evaluate Pro Edition features, you can place BC back into trial mode.

To restore trial mode, close Beyond Compare, then rename the file where your license key is saved from BC4Key.txt to BC4Key.back.  (This is an example.  You will use the key filename corresponding to your version.)

License key location

After you've renamed the license key, run Beyond Compare, then select Help | About Beyond Compare from the menu (or Beyond Compare | About Beyond Compare on macOS).  Check Evaluate Pro Edition features.  Restart Beyond Compare.  When you are finished evaluating the Pro Edition, rename BC5Key.back to BC5Key.txt to restore your license.
