Windows 11 problem with the download of JNLP file

[d3py]

Hi, I'm preparing to install the program, but when I open Java tells me that it has blocked because it does not respect the security conditions (He says he has an expired outdated certificate):

Hi,

that's a known problem, certificate handling for java seems to be really painful.
You just can set an exception (not 100% sure if the names are the same in your localized version):
Try to find the program "Configure Java". There open "security" and search for something like "edit sitelist" for whitelisting exceptions. Add "https://www.stellwerksim.de" and save. Now you should be able to start Stellwerksim.

Have fun
