Thanks for reaching Adobe Community.
It will be my pleasure to explain this for you. You can install creative cloud applications purchased with one Adobe id on two machines.
If you have it installed on only one machine then you can go ahead and install it on the second machine for your wife as well.
Thank you very much for your reply. I did installed them on my Windows partition on MAC and it works perfectly. Until my new MAC arrives I will use it on both partittions. However, I noticed how convinient is and I think I might purchase another license but perhaps on my wife's name as I do not think I can buy a second license.
Yes, you are right. You need to buy the second license under your wife's email address as with one adobe id you can have only one creative cloud subscription.
