How does the licensing work?
Your product key grants the purchaser of the key a perpetual license for ControlMyJoystick version 5.x. This key can be used on subsequent upgrades to version 5 (ex. 5.1, 5.2, 5.3 etc) and can be used on up to three computers owned by the purchaser. So if the purchaser has a laptop, notebook and a desktop, you can use the same key on all three computers.
Can I transfer, give or sell the product key to someone other than the purchaser?
Is it a subscription?
No. The product key does not expire and you do not need to pay additional fees to continue using the software.
