Go to Help > Sign in and see if it is grayed out. If it is, then it is OK.
When I am permanently signed the only option on that menu is Sign Out (my adobe id in brackets). If I do sign out I cannot re-launch the software without signing in and re-entering the license key. Then it works OK again. I have been installing it with my adobe id and my logon user name as an administrator of the local machine. When I log out and delete my user profile from Windows, what will happen when the end user logs on for the first time in his or her own name and tries to launch the software. Will it continue to use my adobe id and stay signed in (I don't mind if that happens) - or will each end user have to setup their own adobe id and be told the license key details in order to activate their own device installations? Not clear how this will work from this point onwards ... Can you clarify before I close this incident?
If you installed as an administrator and allowed all users to access the software, then all users should be able to use the software.
There is no need to sign out unless you need to use the software license on another computer. Just don't sign out and all should be OK.
