Issue with License server file format

Hello, 

for my Master Thesis, I´m working with Dymola 2020 and as the Trial Version is not enough for me, I wanted to upgrade my license using the license server of my university.. Everytime I try to set this up.. I didn´t found any solutions for this and how the file actually should look like..


thanks in advance
