ALERT: Quicken Classic for Windows fails to install under latest Windows 11

rloeb

Problem is that the install contains an unsigned printer driver, which Win11 no longer allows. There's a workaround, but it involves rebooting into safe mode, disabling the driver signing requirement, then installing. (The latest Windows bug makes this especially complicated because it doesn't allow shutdown or restart…)

I would try updating your printer driver, reboot your computer, and then try installing Quicken.

@Grammy605 , Microsoft issued a warning about KB5074109, suggesting users experiencing issues to uninstall it. And presumably yesterday's KB5078127 resolves some of them but not all. I don't think that is your problem but just FYI.
