After Update to QuickBooks the Sync tool no longer seems to be working


The sync between Order Time and QuickBooks Desktop through the sync tool is not working after an update to QuickBooks Desktop. The issue can be spotted by noticing the sync tool will crash when trying to connect to QB. 


The way to resolve this issue is to fully uninstall all versions of QuickBooks, including any previous versions that have been left on the machine, and then Re-Install only the current version QuickBooks.
