My parents both use Macs to do their work and my dad bought three licenses for Microsoft Word on Mac. The problem is that he somehow set up the programs so that only one can be used at a time, meaning if my dad has Word open on his computer my mom can't open it on hers. He's tried reinstalling and configuring the programs to no effect.
I thought of a solution to edit the hosts file on one or both of the macs to prevent Word from connecting to the internet to tell the other computer that it can't use Word. My problem is that I have no idea how to find out where Word connects to do this, or if it is even Word that is doing the connecting.
Working offline is out because both of my parents work and need to use the internet.
I know how to edit the files, but I don't know what I need to block. How would I find this information on my own?
