Quickbooks Desktop no longer working after 26.1.2 upgrade

This morning I *Was* able to fix this using the posted directions from @CoryL1

Here's how to find the Emulation Settings thing!

Find your QB App in Windows (In my case it resides in "C:\Program Files\Intuit\Quickbooks Enterprise Solutions 24.0\QBWEnterprise.exe")

Right Click and choose Properties

Click the Compatibility Tab

Under the section called "Windows on Arm" click "Change emulation settings"

You will see a pulldown with an arrow that likely says "default"

Click that pulldown and you should see the "Very Strict execution" choice at the bottom of that list

Choose that, hit OK, Then Apply, then reboot!

Hopefully this will work for you!
