quicken crash at startup after installing update r21.17 (edited for readability)
after installing the update on 9/7/19 I kept getting quicken crashes on startup. called quicken and they led me thru reapplying the update to no avail and then unstalling and clean reinstalling quicken which seemed to work but 4 hours later the crash was back. over the last couple weeks reapplying the patch helped sometimes. also doing the no file startup and then opening the file worked once. the final solution which I finally found was to run quicken in compatibility mode windows 8. problem solved. runing win 10 update 1903 which itself has been causing random reboots independent of quicken.
