What the Error Means

Error 80040437 comes directly from the Intuit Software Development Kit. The QuickBooks user assigned to QQube is already signed in to the company file from another computer or Windows session.

This normally means another person is using the QuickBooks user reserved for QQube, or more than one QQube Synchronizer is running with the same QuickBooks connection user.

Resolution

Complete these checks in order.

1. Reserve the QQube QuickBooks User for QQube

Create and assign the dedicated QuickBooks user described in Create Connection Users.

Do not use that QuickBooks user for normal QuickBooks work. Sign out any person or computer currently using it.

QuickBooks user assigned for QQube automatic login

2. Stop Additional QQube Synchronizers

In a Multi-User implementation, run the Synchronizer only under the dedicated Windows synchronization user where QQube was installed.

Close any Synchronizer started under another Windows user. A regular server or Remote Desktop user is not a synchronization user.

Use the installation guide that matches your environment:

Expected Result

The QuickBooks user assigned to QQube is used only by the dedicated QQube synchronization session, only one Synchronizer is running, and the synchronization completes without Error 80040437.
