The official license terms in the EULA say this:
2. INSTALLATION AND USE RIGHTS.
a. One Copy per Device. You may install one copy of the software on one device. That device is the “licensed device.”
b. Licensed Device. You may only use one copy of the software on the licensed device at a time.
c. Portable Device. You may install another copy of the software on a portable device for use by the single primary user of the licensed device.
However, I am wondering, if the Laptop I bought is then used a lot by someone else in the Family who lives mostly away from home - I guess this technically breaks the rule in the license?
