Error: "[User] Already Logged in at Terminal [Machine] Under Windows Login Account [Windows Login] Do You Want to Clear This User?" When Attempting to Login to P6 Professional When Connecting to a SQL Server Database

(Doc ID 2327842.1)

Last updated on DECEMBER 01, 2017

Applies to:

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



After the P6 environment was upgraded from 8.2 to 17.10, the message "[user] already logged in at terminal [machine] under windows login account [windows login] Do you want to clear this user?" is displayed at login; selecting 'Yes' allows the user to login and run P6.


This message should not display at login.

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

  1. Login to P6 Professional.
  2. View message.
  3. Select 'Yes' to continue normally.
