What kind of licencing should we use for this case?
In this scenario, you can use the free license as it suits for personal use. Here's a license comparison
table and our EULA
that might also be useful.
Who should be registered as owner of the licence?
You might register the license to Betty's name or to any of her children's names, then register the Viewers with this license key. However, please make sure to have access to the specified email in order to obtain the license key.
Can we use same settings in address book for every viewer for Betty’s laptop?
Of course, using the same settings for each Viewer is advised in this scenario.
In addition, here's a Quick Start
guide that might be helpful.
