To do that, you would need one of:
- Concurrent license sized for 2 concurrent licenses
- Standard/Commecial/Professional individual license (all the same thing), for which the limit is 4 simultaneous installs and 2 simultaneous uses
- "Startup" license -- not sure of the limits on Startup licenses
- Campus-Wide license (academic license only). In the past, there used to be Total Academic Headcount (TAH) and Total Student Headcount (TSH) licenses, but those have seemingly been overtaken by the "Campus-Wide" terminology
In particular, you cannot do what you want with any of:
- Student license
- Home license
- Dedicated Computer license
All three of those license types are restricted to installation and use on a single system.
There have been reports from some people who have been able to install Student licenses or Home licenses on two systems and use it on one system at a time, but there have also been reports from other people that they tried to install Student licenses or Home licenses on two systems but were unable to do so.
