The number of installations permitted by the Golden Software license agreement is dependent on the type of license that was purchased.
The Golden Software single-user license agreement permits the software to be installed on three computers, but it can only be used by one user and cannot be used concurrently. To that purpose, standalone licenses of Surfer can be activated on only two computers at a time. If the software is needed on a third computer, a license can be deactivated on one of the computers and then activated on a third computer. Activations can also be viewed and managed through the My Account portal.
Concurrent Use Licenses:
The Golden Software concurrent use license agreement permits the software to be installed on multiple computers and used by you or anyone within your organization. However, the number of simultaneous users cannot exceed the number of license seats. To that purpose, only one activation is provided for the server computer. It is not necessary to activate each Surfer or Grapher installation for concurrent license use.
