The latest Windows 10 update that installed 6/17 made QBD 2019 no longer compatible with Windows 10 thereby forcing users to "upgrade" to the Intuit subscription product in order to open a company file in QBDT 2019 (even though one does not use any of the internet-based QB services).  Unreal!  And what a coincidence that this happened only days after Intuit ceased supporting QBDT 2019.... Can you spell collusion?
