UAC - Run All Administrators in Admin Approval Mode GPO breaks IE integration

Hi,

We are having an issue with Adobe Acrobat XI version 11.0.23 on Windows 7 x64 SP1 with IE 11.

I have found that when attempting to view a PDF document in IE, the document will not load and will show a black X in the top left of the IE page.

If the following Group Policy object - Local Policies --> Security Options --> User Account Control --> Run All administrators in Admin Approval Mode is set to Enabled then the PDF will not display.

If I change the GPO  Local Policies --> Security Options --> User Account Control --> Run All administrators in Admin Approval Mode to Not Defined then IE will successfully display the PDF.

Changing this GPO setting is not an option for us.

Has anyone seen this before and has a solution?

Thanks,

Ben
