WebStore, Ansys Updates for License Manager 2021 R1 affects versions 2017 to 2020 R2


A quick summary: After updating the Ansys license manager and license file to 2021 R1 on the license server, Ansys Mechanical Suite, and Ansys Electronics (EM) Suite all versions from 2020 R2 back to 17.0, on client installations will experience license errors. The current release, 2021 R1, of these suites is NOT affected.



  • Ansys Suites for Linux and Windows


  • All customers using an Ansys Mechanical Suite version 2020 R2 back  to 2017 are affected.
  • All customers using Ansys Electronics (EM) Suite version OLDER than 2020 R1 are affected.


ANSYS rolled out updated license increments to their customers as part of their commitment to deliver a simplified, modern licensing experience. With the December update, WebStore installed a new ANSYS License File, which is required as part of the renewal process, to use these updated increments.  As a result, all versions of the Ansys from 2020 R2 back to 2017 will not be able to use the new license.
Starting 12/6/2021, license preferences will need to be manually reset or the 2021 R1 version of the Ansys Suites will need to be installed.
Ansys Electronics (EM) Suite, includes Electronics and Systems
Electronics software older than 2020 R1 is not supported by these new licenses. Please update to at least 2020 R1 or newer.
