I have followed all of the previous instructions to get Quicken to work and all failed. Finally I completely uninstalled and then reinstalled and have same issue. Launch Quicken it shows in task bar but will not open. Need assistance to resolve this. On brand new Dell with Win 11 Pro. Worked fine for past week just started doing this today.
Additionally I have Quicken Classic. Only way to close is to use task manager to end program.
