I downloaded the QuickBooks Tool Hub, clicked on Installation issues and there are NO option Add Defender Exclusion! I have 1) QuickBooks Install Diagnostic Toll and Optel QB Insall Folder, 2) 3371 Error Fix.

This is frustrating, can't work this morning and have gone through 2 recent updates that took over an hour! Why are you doing this? To make us want to switch to QBO?
