Error 16 - Enterprise

Hello!

We have deployed Adobe Acrobat DC to our company and most, if not all, users who try to view PDFs from IE (using the "open" option) receive an 'Error 16' error message. We have exhausted all efforts and are hoping someone else out there has experienced this and has a solution. We've contacted support and have gotten nowhere.

Full error -

Please uninstall and reinstall the product. If this problem still occurrs, please contact Adobe tech support for help, and mention the error code shown at the bottom of this screen.

Error 16

We have tried...

Making the user a local admin on their PC

Granting full permissions to all Adobe filed in ProgramData and Program Files.

Uninstall, clean with Adobe Cleaner, Reinstall

Fresh install on a new machine (which will sometimes work, but then breaks later)

Monitor traffic on the firewall and proxy for blocks (there are none)

Please help!
