I found the solotion using registry settings, although I was trying so many different things, that was not fully sure wether each one is actually needed. So to make this post, I have been doing some fiddling with the settings I ended up with. The following settings you need:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown
- bIsSCReducedModeEnforcedEx, DWORD, 1
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown\cServices
Change their values or create them.
Using these settings will make the SignIn button at the top right corner go away (But signin is possible through HELP in the menu) and Axcrobat will work as follows:
- If you start it, it will start in reader mode. Modules/options that require a license will be visible, but give you a message you cannot use it
- If you then sign in using an adobe account that has a license for the pro version, then blocked modules will be unblocked and you can do what your license allows
- When you sign out again, Acrobat will close. After starting it again, it will again be in 'reader' only mode
Since these registry settings are in HKLM, they apply to all users of that machine.
