And now, the only move to make is to go on subscription. Eventually, you will have to make that move forward. That’s a nice thought, but there are other factors at play here like aging computers and operating systems, upgrades in drivers or lack thereof, industry demands, and better tools within the software.

Some folks have decided to purchase perpetual software on maintenance subscription believing that they will be allowed to hold onto this software and never have to purchase Autodesk software again. At this point you are only entitled to run the most current version at the time you canceled subscription.

The moment you do that, you no longer have the permission to run the 2015 software anymore because you lost the benefit of legacy version usage. Two years go by and you decide to drop the maintenance subscription. You purchased this 2015 license and was in good standing on a maintenance subscription. However, when Autodesk releases the 2019 in the near future, the permission to run 2015 software drops and you are only entitled to use 2016-2019. This means that if you currently have an active maintenance subscription on a perpetual license, then you can use 2018, 2017, 2016, and/or the 2015 version without any problems. As long as you’re on an active maintenance subscription you have the permission to run the latest released version and/or three prior versions. And so long as you keep paying that maintenance subscription you are entitled to the next version (so 2015 upgrades to 2016, which then upgrades to 2017, and then once again 2018). You may have originally purchased an AutoCAD 2015 perpetual license on a maintenance subscription. Usage permission is based on the history of the serial number.įor example. Just because you may have purchased the right to run a given version of Autodesk software doesn’t mean you are entitled to use it for eternity. Now If you want to read all the legal jargon about the permissions to use previous versions of the software feel free to read about it on Autodesk’s page, Previous Version Rights Benefits Terms for Autodesk Maintenance Plans, Subscription for single-user and Subscription for multi-user.
