FileBot

About six months ago, I bought a Windows license that would last for one year. My next step is to install Filebot on my Linux desktop as well. I would want to get a permanent license that is compatible with the new Linux machine; but, I am unsure of how to install it on my current Windows machine, which already has a valid license.

You can use the same 1-year license on both your Windows machine and your Linux machine.

If your currently installed license has expired, then FileBot prompt you to select a new one. FileBot will also give you a "Renew License" button to purchase a new 1-year license and a "Upgrade License" button to purchase a new life-time license. There's nothing special about these buttons though. They'll merely open the online checkout with your email address pre-filled from your current license.
