Through Windows Command prompt, you can execute different commands associated with subscription licensing like activating, deactivating, viewing licenses, etc. Please find below the steps to execute these commands:

1.    Launch the Windows Command Prompt from the start menu by typing “cmd”.  Right click the Command Prompt application and select Run as Administrator.

2.    In the command prompt, type in:

For version 2021R1 and later:

cd C:\Program Files\ANSYS Inc\v211\licensingclient\winx64

For older versions:

cd C:\Program Files\ANSYS Inc\Shared Files\Licensing\winx64

(this is the default installation directory of Discovery products. If you have installed it at a different location, enter the appropriate path where ansysls_client.exe is present)

3.    Once in that directory, run the following commands:

Activate license:

ansysls_client.exe -ActivateLicenseEntitlement < ActivationID >

This command can be used to activate license on your machine. In above command, replace < ActivationID > with your activation id. You can find the activation id in the txt file that you receive or from your Discovery Account page under Manage Subscriptions section.

Deactivate license:

ansysls_client.exe -DeactivateAllEntitlements

This command deactivates all the active licenses assigned to you. After deactivating licenses, you will be prompted to sign in when you launch any Discovery product.
