Since latest updates, Quicken Deluxe crashes constantly using Windows 10 Pro. R53.16. ; 27.1.53.16.
Crash will even manifest itself when creating a new Quicken file. Crash occurs when I attempt to add the first account. So far Quicken support folks (more than 3 hours on the phone with them) have been unable to determine the problem. Crashes do not occur on Windows 10 Home platform.
