Last updated on MARCH 22, 2022

Applies to:

Primavera P6 Enterprise Project Portfolio Management - Version 18.8 and later
Information in this document applies to any platform.


When a user attempts to login to P6 Professional hosted on Citrix while another user is already logged in (using their own P6 account), the following error occurs.

<new user's name> is already logged in at Terminal <computer name> under Windows login account <existing user's name>. Do you want to clear this user?

If the the user clicks Yes, the other user is kicked out of their P6 session.  As a result, only one user at a time is able to login to P6 even though they are each using different P6 accounts.


The issue can be reproduced at will with the following steps:

1. First user logs in to P6 hosted on a Citrix server.
2. Second user attempts to login.
3. The reported behavior occurs.
