As gsconsult has indicated and backed up by our own testing with QB2021 MOST RECENT UPDATES, QB does in fact refuse to start if IE is not installed. IN addition, some portions of the help system STILL make calls to IE, despite QB claims to the contrary.

And while QB may CLAIM to have a new browser, it would appear that it is still making calls directly to the old IE engine components, but that is what happens when you leave resolving an issue you've know about for several years until the month before it is scheduled to stop working.

QBOnline is just another (expensive)disaster waiting to happen as it is still highly selective as to which commercial business requirements it supports and from what we;ve heard fomr others, the suport is NO better.

Suffice to say, our migration away from Intuit is now complete so our only exposure to QB is an archive VM that we are keeping for audit purposes. 

Continued inattention to this and other issues and general ineptitude when it comes to the product has been the death knell. Its rather clear that Intuit's vision forward does not really include a viable desktop version product and are doing everything possible(including crippling the product) to force clients to "convert" to its On-line cash cow version.

Very disappointing after many customer years...
