Cannot disable Reader DC IE Plugin
I am trying to disable Adobe Reader DC Internet Explorer plugin on about 100 computers. I need Adobe Reader to run inderpendantly. I can do this with other apps via Group Policy but not with Adobe Reader.
If I disable the ActiveX pluging manally like so (as per Acrobat Help | Display PDF in browser | Acrobat DC, Acrobat Reader DC😞

...PDF documents still open from within the browser. I can see Reader is running within Internet Explorer:
How can I disable the plugin?

Version details:
I am running Windows 8.1 64-bit but I am having the same problem on other Windows 7 SP1 32-bit PCs.
Adobe Reader version 2015.007.20033
Internet Explorer 11.0.9600.17842
