Downgrading would basically take almost the exact same amount of time.

This should really be a 5 minute job to fix it, but instead they do nothing. Signing an executable is nothing more than running a program to sign the existing executable, which just embeds some information into the the executable. Running this app might put your PC at risk ' I would like to understand what I need to do make my app reliable. Windows Defender (and I'm guessing the other anti-virus software) is reacting to the installer program not being signed, not the actual Quicken program. Microsoft Defender SmartScreen prevented an unrecognized app from starting. There really isn't any reason for them to downgrade the update. It is just possible that it has indirectly caused other side effects such as this one (not saying it has, rather just possible depending on their system and how their AV handled it). The responsible thing is for Quicken to remove the R43.14 auto-update (and the Mondo patch) and replace it with the older one ASAP until they resolve it in the next one. Sign it and release it again, but instead it seems that Quicken Inc is fine with users having to jump through hoops to use it.

You would think this would be a simple fix. Note this is why not only Microsoft Defender is having problems with it, other anti-virus software is also calling it out as a problem, even quarantine Quicken over it.
