Hello Annette
Thanks for reaching out in the Community. Sorry, there is no provision to have 2 Dropbox account on one Desktop. IF the PC has several desktop (users with their own Desktop) then yes, that is possible but only one instance running, However, you can view both accounts by doing what this Article says: https://help.dropbox.com/account-access/switch-between-accounts
Does this answer your question?
were you wanting to know how to change to another account?
See the article linked above and go to the Heading:
Switch accounts in the Dropbox desktop app
