Hi team

I am facing issue regarding that NI license manager showing NI Teststand 2014  is licensed wheres while opening teststand application which shows activation required on 1 particular PC alone.

if anyone faced this issue, pls do the needful.

Note: It is activated through Network License Manager. Other PC's  which are having  NI Teststand 2014 , working fine

If I understand correctly, TestStand should pull a Network License, but doesn't

Assuming that the PC has been restarted after installation....

You may see a "Zombie Local License" that TestStand is sticking to. You can find local licenses at C:\ProgramData\National Instruments\License Manager\Licenses

Emptying this folder (after backing it up of course) and Restarting my solve this issue

After Emptying this folder C:\ProgramData\National Instruments\License Manager\Licenses  and Restarted PC, Issue is not resolved.

any other possiblities?

Can you try re-entering the license server and re-establish the connection?

Oh.... and can you double check on the license server itself, that the license is assigned to the PC and active?

The fact that you are using License Manager 2025 could be your problem. With LM 2025Q1, NI updated a library that broke compatibility with older license servers. I know because this happened to me. Corporate is using an older version of FlexNET and upgrading my license manager to 2025 broke my ability to pull a license.
