Windows Server 2016 - Error 195

Hi,
i have been trying to install Photoshop CC 2019 v20 for around 3 hours now without any luck.
I assume its because i run Windows Server 2016 as my OS.
I open the installer and after chosing the destination i get prompted with this screen:

My hardware should be more than capable of handling that, but for reference, i list the major components:
i7 5930k,
32GB DDR4
GTX 980 Ti
Samsung 850 Evo 500GB

If i run the installer in compatibility mode for windows 7 or windows 8 i get greeted with Error 190 and the following details:

Exit Code: 190 -------------------------------------- Summary -------------------------------------- - 2 fatal error(s), 0 error(s), 0 warnings(s) FATAL: Sanity check for installation failed. Current OS version 6.2.9200 doesn't satisfy OS requirements. FATAL: Error occurred in install product workflow with error code 190 error message -------------------------------------------------------------------------------------

My system is on the newest windows update, all my drivers are installed correctly and i dont have problems with any other programs besides Adobe ones right now.
I am kinda clueless what to do now (and yes, i did try to turn my system off and back on again.).

If anyone has an idea on how to fix that problem, please let me know.

Thanks a lot.
