Add apps to an specific user

Hi there, silly question: my wife has her user on our iMac and she has her own adobe software I have mine and other specific software and sometimes it's confuse because our adobe ids, the easy solution is create a new user for me with my adobe software so in that way we can avoid confusions with the adobe IDs but we don't know how to manage or add the apps for user, even we tried to open my user and install a app in this one but it did'n work.

Any Ideas?, thank you.

Carl.
