Adobe Acrobat Reader on Windows 2019 access denied

Hi guys, hope all is well.

I am running Acrobat reader on a Windows 2019 server inside a Domain and the programs opens just fine when I run it. However, if I try to add a digital signature I get an access denied error. Even if I log as a domain administrator I get the same error on the \User\username\Appdata\Roaming\Adobe... etc leading to the adobe files inside that folder. So I can't import any certificates and its becoming annoying.

Even as the admin I can't.

Any of you have a workaround for this? Its Windows Server 2019 Standard and its inside a domain. Even with full admin rights I can't make it work.

Thanks
Teo
