Adobe Acrobat Reader 2022.001.20117 ADMX Files

Hello Community,

i have a really big problem with the Adobe Acrobat Reader DC Version 2022.001.20117.

The newest ADMX Files for the Management i could find in "ftp.adobe.com" are from 2015.

When using those ADMX files in the goup policy the Reader compleatly ignores the policy.

Using "gpresult -r" i can see that the group policy is used by the Computer. 

As soon as i open Adobe Acrobat Reader i get a splash screen (wich i disabled in the Policys) and in "Options - Security - extended"the Secure Mode on Startup is activated. Wich i also disabled!

Its driving me crazy and i can't import any PDFs in our ERP System. Thats a huge issue for the Company and the Support won't help because it's just the Reader DC.

Does Anyone have newer ADMX Files or any idea what registry Keys i can Use to disable all Messages, the Security Mode on Startup and the Splash Screen? It would really help me!
