In the account management window, click Sign out to log off from PowerBuilder.
The login window pops up immediately after you signed out.
Signing out does not need to reassign the license to user. The user account can still be used to log into the PowerBuilder IDE (same or different one) again.
If you are unable to click Sign out to log off from PowerBuilder, you can ask your license admin to use the remote logout on the Appeon website (see the section called “Logging out users” for more).
You can also select the Sign out on exit option in the login window or the account management window to automatically log out the license when the PowerBuilder IDE is closed in a normal way and with network connection.
