When you purchase vRigger, you receive a "license key." Your license key is displayed on the screen immediately after placing your order and is emailed to you.
Your license key "activates" vRigger so it can run on your computer. It also controls which rigging industries are supported by vRigger. You should not share your license key with other people or you will not be able to run vRigger.
Each vRigger license allows you to run vRigger on one computer. The license also allows you to run vRigger on a second computer (e.g., a laptop) if vRigger will be used by the same person.
If you purchased multiple copies of vRigger at one time, your license key will permit the software to be installed on multiple computers.
