CRITICAL SECURITY ISSUE: For machines that already have the FLEXID9 (Sentinel/Aladdin USB) dongle driver installed, Flexera strongly recommends updating older versions of the dongle driver to version 7.90 to address vulnerabilities related to possible exploits of port 1947.

When using dongles, after installing a new release of the Ansys License Manager, the dongles may not be recognized again by the license manager until the licensing configuration process has been completed by handling the manual steps detailed in this section. To avoid affecting currently running Ansys jobs, you will need to use caution when upgrading the license manager.

Only the dongle driver that is included as part of our installation files is fully supported by Ansys, Inc. The driver version required for Release 2024 R2 is detailed in the File Information and Supported Dongle Driver Versions section below. We strongly recommend that you use this version of the driver. If you use any other version, including older versions that we provided, Ansys, Inc. can provide only limited support if you encounter problems. Flexera has stated that they will not provide any support for drivers other than the version that we include with our installation.

Due to requirements of non-Ansys products that are installed on the machine or because of operating system levels that Ansys, Inc. supports but the driver included in the Ansys installation does not, you may need to use a version of the driver other than the one that we provide. You will need to choose which driver to use based on your individual business needs. Unfortunately, we cannot ensure that our license manager will work with that driver.
