I can't tell what method Adobe uses, but I know users who have had one of their two copies deactivated.
Thank you for your reply. That's a shame. I fully understand the reasoning but it would have been nice to just flick between them with ease; I guess it's not worth the risk, hey ho.
ave the program open on two of my computers here in my household at the same time; of course I'd only be actively at one computer at any given moment so not technically using the other, but it would be open.
My experience with this is that nothing deactivates but, upon launching the second copy on the same network, a window appears saying that two copies have been launched and the first copy should first be closed if you wish to continue using the second copy.
So I've never been able to run the software on two computers simutaneously on the same network.
