Caution: Do not allow Windows Update to install later versions of the dongle driver as this is not the Flexera-provided version. Automatic updates can cause unpredictable behavior with dongles, such as:
Features that require the dongle cannot be checked out.
The dongle FLEXID (hostid) is not returned correctly.
The dongle driver cannot be removed using the methods described in this document.
Caution: Removing a dongle or its driver may seriously disrupt your ability to run any product that uses it. Therefore, do not remove a dongle or its driver until you determine that all products that might be using it have been closed. Always stop all license managers that use the dongle and remove the dongle from the system before removing any existing driver. (These steps are detailed below for the Ansys License Manager.)
To install the Ansys-supplied driver on Windows systems, follow the steps below. You must have system administrator privileges to install this driver.
Install the Release 2026 R1 Ansys License Manager.
Confirm that the license manager is stopped by verifying that the 'Ansys License Manager' service is not running.
Remove all FLEXID9 dongles attached to your machine. Do not attach any dongles to the system again until told to do so in this document; if a dongle is plugged in before you have completed the driver installation, the Windows operating system could automatically install a non-Flexera driver.
In Windows Explorer, navigate to the following directory:
C:\Program Files\ANSYS Inc\Shared Files\bin\winx64\driversExtract the contents of the FLEXID9_Windows_v10_13_x64.zip file into C:\temp.
Open an administrator command prompt window and perform the following steps:
Navigate to the following directory:
C:\temp\FLEXID9_Windows_v10_13_x64Issue the following command:
haspdinst.exe -install
When the installation completes, restart the machine.
Note: You may not see the new driver until the dongle has been inserted into the machine. However, do not insert the dongle until the next step.
After the machine has restarted, insert the dongle. Wait until the dongle's LED light is red and is not flashing. If you have multiple dongles, wait until the light is red (and not flashing) before inserting the next one.
To see if the dongle is being recognized, open the Ansys License Management Center and click the Get System Hostid Information link. If the dongle is recognized, you will see a FLEXID9 Dongle ID (F) entry under the IDTYPE column. (You can open the Ansys License Management Center by clicking the Ansys, Inc. License Manager > Ansys License Management Center item on the Windows Start menu/Apps page.)
