Software Install Restricted, No Go?

So, my work phone is crippled, can't install much of anything (an S5). I can install the Gear Manager, but when I try and pair with the phone, the jagoff admins set the phone to uninstall the required downloads the manager is trying to install (2 of 2, it says). So, as soon as they install, the are uninstalled. And the pairing hangs at that point.

I tried with my personal S6 Edge+, and it works like a champ. But I want it for my work phone. Am I dead in the water? Return the S2? I can't see a way to make it go...
