ITrack/Quickbooks/Error 520 - Could not start quickbooks

Cause:

This error occurs because ITrack can not find the QuickBooks company file.

Solution:

Click on the Browse button in the Quickbooks Toolkit, then navigate to the correct Quickbooks file and select it.

Iterations of this problem

The Quickbooks company file can be unable to be found for various reasons, because there are various ways customers host the file.

The File is hosted by some service that has gone sideways

In the example of Concrete Trucks & Equipment, the Quickbooks file was hosted on Microsoft One Drive.

One Drive moved around user profiles and permissions which caused ITrack not to be able to communicate with Quickbooks even though we had the file open in Quickbooks desktop alongside ITrack.

Always consult the IT professionals about where and how the company file is hosted.
