License issue for Fluent


I am trying to take license from the server machine for Ansys Fluent 2019R3. We are using Ansys Academic licenses. When I configure the Client ANSLIC_ADMIN Utility for license server and check the status I am able to connect the server machine,

However, when I open the fluent, it showing the following error:

Hit return to exit.

Unexpected license problem; exiting.


Except Fluent, I am able to open CFD-POST and SpaceClaim. When I open Set License Preference for User, 2019R3 in Client ANSLIC_ADMIN Utility, it shows the following licenses,

Except my laptop, the fluent and other products are working fine in other PCs and Laptops using same server and licenses. The only difference I can see between my laptop and other PCs is in the Set License Preference, my laptop shows only ‘ANSYS AIM Pro’ in the Solver window; whereas, in other PCs, there is one more license named ‘Ansys Academic Research Mechanical and CFD’. This license is not available in my laptop. Can anybody suggest how to resolve this problem?


(i) I have check connections from my laptop to server and vice versa. Its communicating via ping and Telnet (1055, 1056 and 2325).

(ii) I have tried by completely removing the Ansys including window registry form the laptop and reinstalling of same version and also checked with 2020R1 and 2020R2. The problem is same in all the cases.

 In this regard, some help and guidance will be highly appreciated.

Thank you.
