I have a client on the phone who unfortunately does not know his Windows and Internet Explorer version. I'm trying to debug an issue they're seeing, but in order to reproduce it I will have to find out what version of IE they run.
What would be the easiest way to have him get me the information, via phone?
Note that I cannot send him any URL that he could click, and he can't create screenshots for me. And I, as I have a Mac and no Windows installation, cannot even test out all the various possibilities…
This is somewhat related to finding out the Windows version, but that's secondary to my problem.
