We are looking to know the microsoft office version installed on the BYOD's used by my employees to install a fresh licensed version for our employees.

Is there a way to know the Microsoft office version on the BYOD's as thick client - native mobile applications are not allowed.

The solution should be able to do the following:
- Get the BYOD device details - which user agents of the browser can provide(i guess)
- Get the Office version installed(??)

Any suggestions or thoughts are appreciated.
