You can have a 32-bit version of MapInfo Pro (version 15.x or 12.5) on the same computer as this 64-bit version regardless of the licensing model you are under. The actions when activating and returning, and whether you can borrow a license, are different depending on which license you have.
Node-Locked Licenses
Licenses come from the Precisely FNO Server. When you install MapInfo Pro, you can activate the licensing immediately or do it later during the 30 day courtesy period. Activating it gets you a license from the Precisely FNO Server that is node-locked to your computer. When you install the 32-bit edition of MapInfo Pro, you will not need to activate a license. The same license is used for both installations.
Take precautions when returning licenses if you have a 15.x or 12.5 license checked out and both 32- and 64-bit versions of MapInfo Pro installed on the same machine. The 32- and 64-bit versions use the same license. If, for example you return the license for 64-bit MapInfo Pro 15.2 then your 32-bit MapInfo Pro 15.0 will no longer work.
For more information, see Node-Locked Licenses.
Concurrent License
Concurrent, or floating licenses, come from a license server that your organization has purchased and maintains. You will need to know the name and port of the license server to activate a concurrent license. You can activate the license during the installation process or when you start a MapInfo Pro session. Each session of MapInfo Pro on a computer requires the checkout of a concurrent license. However, the same user using both instances of MapInfo Pro on same machine will not cause another license to be checked out. When you end your session, the license is returned to the server.
Borrowing a Concurrent License
Borrowable licenses are concurrent licenses that are borrowed for use on another computer for a period of time. This allows you to run an installation of MapInfo Pro that is not connected to the license server, for example on a laptop while traveling.
If you have both 32- and 64-bit editions of MapInfo Pro on the laptop, the borrowed license will be shared with both editions. When you return a shared license, you will have to reconnect the laptop to the license server network to get another concurrent (floating) license to continue to use either edition.
For more information, see Concurrent Licenses.
Distributable Licenses
The distributable licensing model allows companies to "distribute" licenses using your MapInfo License Server, which is available for download. This model is for customers who have limited access to email or to the Precisely FNO server. Distributed licenses follow a similar activation procedure to other models that are handled using your License Server. For instructions on installing the License Server, see the License Server User Guide.
For more information, see Distributable Licenses.
Universal Licenses
Organizations who purchase universal licenses are provided with a special license that they make available to their MapInfo Pro users. There are no special requirements or handling when both 32- and 64-bit editions are installed on the same machine.
