    The hosted units are linked with the Windows user profile in a way. So to solve that license issue there are two solutions :

    1. Solution1 is to make sure CSS (creating the Flux servers) has the same rights as you do in terms of license. Otherwise it only looks locally for the file or for the environment variable.
      So you need to go to Windows Services and find "Cedrat Soft Server" service. In the properties, "Log on" tab, you need to use your Windows credentials so that the service runs with your profile.

      For this solution, you don’t need to be connected to a given network. It should be your Windows credentials. Then stop/start the CSS service and it should work again from what I understood.

       

    2. Solution2 is to make sure the token you have from hosted units is valid for the whole machine instead of one specific user.

      For that you need to generate a new token and use the given command for almutil tool :

      -hhwuauth       [-system -code <code>]

                       Authorize with the Altair Hosted HyperWorks Units system.

                       -system will set system-wide authorization.

                       -code the authorization code you receive from the web portal

       

    Solution 1 is easier and should do it.
