Hi Bill;
This could be because another instance of PB is still open on another PC with your login attached. This can still happen using R3 as well if you left the IDE running and the PC locked and then tried to login / restart a R3 session on another PC.
Regardless of your PB2017 revision - the key now is to remove the lock on your named instance. You can do this by:
- Locating the other PB2017 instance. Select the "Account Management" on the PB IDE's top right hand corner and then in the next dialog actually select the "Logout" link.
- The other alternative is to login to the Appeon website and enter the User Center. Once there, select: License Management => PowerBuilder IDE => Release User and then force a logout via the "Release" link on your active session.
Note that you may not have the privileges in the User Center if you are not your company's License Administrator. If that is the case, then you will need to contact your License Admin to perform #2.
HTH
