Our current Licensing Policy for Ancestral Quest is rather lenient and generous, and is a one per household per platform license.
Once you purchase an Ancestral Quest for Windows Registration Key, we allow you to use that same Windows registration key on all the Windows computers that are regularly used by the members of your household. So, you can install AQ onto your additional Windows computers, as long as you are the primary users of those computers (and you remove the program should you no longer be using any of those systems).
You can use the CD, if you have it, to install the program onto both computers, or you can download the program from our website onto each computer (or download it once to a flash drive and run the installer from that flash drive on each computer). You will just need to enter your Windows Registration Key into the program on each Windows computer.
A purchase of an Ancestral Quest for Macintosh Registration Key allows you to use that same Mac registration key on all the MacOS computers that are regularly used by the members of your household. So, you can install AQ onto your additional MacOS computers, as long as you are the primary users of those computers (and you remove the program should you no longer be using any of those systems).
Households with Mixed computer platforms
The Ancestral Quest Registration Keys are not interchangeable between Windows and Mac systems. So, if your household has one or more Windows systems as well as one or more Mac systems, you would need to purchase both a Windows and a Mac Registration key.
You do not have to pay full price for both platforms, however. Once you have paid 'full price' for any version of AQ, we consider you a loyal customer, and all future purchases of any version of AQ can be done so as an 'upgrade.' (At Incline, our use of the word Upgrade on the purchase screens does not always mean you are upgrading from one version to another of the same platform, but is to basically let you purchase additional licenses of AQ at a discount, as all 'Upgrades' are at a reduced price.)
This policy is effective as of 1 January 2020.
