Error while installing app
Most organizations don't want to allow use of company software on rooted device as it is considered undesirable for following reasons:

Warranty – Some manufacturers assert that rooting voids your device’s warranty. However, rooting will not actually damage your hardware.

Security – There are some security issues, like Google Wallet, in particular, has a vulnerability on rooted devices that could allow other apps to access your PIN and other wallet information.  Google Wallet displays a warning message if you run it on a rooted device. 

Bricking – Rooting a device is a very safe process. However, there’s always some danger of “bricking” a device when you go outside the normal parameters and hack around with it — particularly if you’re trying to root a device or operating system version not supported by a tool. “Bricking” refers to breaking the device, making it about as useful as a brick. When you root, jailbreak, or install a custom ROM, or otherwise hack around, you do so at your own risk. It’s a good idea to do a little bit of research first and see if other people report success rooting your device.

AFAIK, you have 2 choices 

1.You need non-rooted device to install your company's proprietary software 2. you may reach to IT Dept. of your company and request them to allow installing  company's proprietary software on ROOT-ed device. They need to disable the checking of rooted/non-rooted device while installing the software.
