I have a one login I'd and password in Adobe. Use my login I'd and installed Adobe InDesign in one system. Again use to my same login I'd and installed Adobe illustrator in another one system if it's possible or not. Kindly let me know the Adobe rules.
Note: I have purchased 2 softwares in single account.
the only (insignificant for internet connect computers) limitation is that you can sign-in (and therefore start your adobe programs) on, at most, two computers at any one time. because you can sign out from either (or both) signed-in computers using a 3rd computer, this could not (imo) be easier.
