2 instances of eM client on the same windows 10 machine?

Windows 10. Can 2 instances of eM client be installed on the same windows machine in order to run in parallel, each with unique email account?  Same windows account profile is shared by two users. (eg think aging grandparents…).  Once instance of eM client, with multiple email accounts, does not provide a user experience this demographic can successfully manage.  Much appreciated.

No, that is not possible. If they were using separate Windows profiles, no problem, but eM Client does not support separate user profiles in the same Windows session.
