HELPDESK_WJ (Waijung)

Hi everyone,

when trying to install Waijung 2 using MATLAB R2025b according to the install instructions, I cannot open the license manager (step 5).
Running install_waijung2 in MATLAB runs sucessfully with the following output:

When then clicking on the Waijung License Manager app, I'm getting the following error:

Closing and re-opening MATLAB does not help and delivers the same error message, when clicking on the Waijung License Manager app.
