Licenses not working in WORKS

Hello,

I have bought the WebIQ 1 Year license. On the Readme of the colleberation room I read that i should activate it via: 

Activate PC-based Designer license in ctrlX WORKS (Settings>Licenses>Upload license file)

I am using a Virtual Machine to run ctrlX WORKS. In my VM i'll get the following error when I am opening License in WORKS:

(Error text: HTTP server error
Internal server error (500) · A service system error was encountered: Failed file open. [1,7E5,9,0[73000041,5,400703F3]] · 080F0200 · 0C7A0200) 

What is weird is that the Licensing in WORKS does work in my host. I do have a good internet connection in my VM. 

I want to use WebIQ in my VM. What should i do to get it working in the VM? 

Kind Regards
