How Licensing Works

A Macabacus license is valid for any supported Office version, and is not associated with any particular Office version. For example:

  • You can activate Macabacus in Office 2016 at home and in Office 2013 at work using a single license.
  • If you upgrade from Office 2010 to Office 2016 you need not purchase a new license (but must install Macabacus for Office 2016).
  • You can reassign a license (seat) from one user running Office 2013 to another user running Office 2016.

Each individual Macabacus user requires a license. We do not offer site licenses. Licenses may not be shared by multiple users, but can be transferred among users (i.e., remove one user's access and then reassign that "vacant seat" to another user).

When you activate Macabacus using an email address as described above, the Windows user account you are logged into becomes "authorized," or associated with that email address. You can authorize up to two Windows user accounts simultaneously through activation, providing a single user access to Macabacus on up two computers in most scenarios (e.g., work and home PCs). You can actually use Macabacus on any networked or virtual PC (e.g., a conference room PC), provided that you log into Windows using an authorized Windows user account.

Sharing Access Prohibited

Both Windows user accounts authorized via activation with a single email address must be used exclusively by the same person. Sharing email addresses among users for the purposes of activating Macabacus is prohibited, and may result in suspension or termination of your Macabacus services.
