Hi Guys,

I came across a problem when I tried to open Fluent, you may find it below.
Any idea? What is wrong?

Check your licence file or re-install it

Fluent cannot find your license file! It does not say that it has expired just that it can no longer be found. Did you move it?
To look for it you can right click on the "my computer" icon on your desktop -> Advanced tab -> environmental variables. Then find the LM_LICENSE_FILE variable and check the directory is correct (go to it and look for the file).

Hope this helps.

If you are sure that you have a valid license file and everything is done as given in instructions, You can go to

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

And run all the .exe files present there. This turns on all the servers. And you might get lucky.
