There is an error in the log similar to this:
This error comes directly from the Intuit Software Development Kit (SDK) and indicates that another user has logged into QuickBooks using the same user name you assigned for QQube to auto-login to QuickBooks.
There are two possible causes:
Cause 1. Create the special "QQube" user per our How-To Guide, to connect to QuickBooks, and ensure that no other person logs in as "QQube" to use QuickBooks.
Cause 2. The synch takes place under the user where QQube is installed. However, regular users, in a multi-user implementation, may erroneously attempt to run the synchronizer under their own user name (or erroneously install an update under their own user name causing the synch to auto kick off), and cause errors like this to occur. A regular user is never a synch user unless you have a single-user on a workstation or laptop. If you are unfamiliar with the proper implementation, please review our installation guides.
