It works on my system that no longer has IE installed on it!  Windows 10 Version 21H2. 

I tried for almost an entire day to hack my way into getting IE re-installed but no luck.  This workaround is really a "hack", but I'll live with it until Intuit fixes QB the problem or I can lay QB to rest for good.  My belief is that Intuit wants everyone on QB Online and wants to get rid of the Desktop version for good.  Intuit has always been about how they can generate revenue for themselves, not fixing the problems with QB that we users have to deal with.  When June 2022 comes, the QB s**t storm will blow up and there'll be more upset QB users.  I'm hoping that in the end it would take Intuit down or at least to their knees.  But I'm not betting on hope.

Just a note.  The Registry hack (adding back in the Windows registry entry for IE that QB is looking for) also works just fine on Windows 11 and QB Premier 2020 Desktop.  Microsoft updated my Window 10 version (above) to 11 without my express approval and QB went south again under Windows 11.  I just created the required Registry update file as explained and documented in the attached PDF file.  I clicked on the Registry update file and it added the IE entry back in (although IE isn't and doesn't need to be actually installed!) . P.S. - make sure you backup your registry before applying the fix, just to be safe.  Also note that this file is being sent with a ".pdf" suffix. It contains the instructions to create and execute  the simple Registry entry update file described above.
