My Quicken 2017 sucks! It crashes every 3 - 5 keystrokes! HELP! I want my 2016 back!

1) Uninstall / QCLEANUI / Reinstall (Q2017)

I recommend you uninstall Quicken using this procedure and following it exactly:

When done, reboot your computer and then reinstall Quicken from your CD (or saved downloaded installation file) and allow it to update to the latest available patch release level. Your Antivirus software needs to be temporarily disabled for the entire duration of the installation and update process. See here for more details:  https://www.quicken.com/support/quicken-2017-windows-release-notes-updates-and-mondo-patch

2) Validate

You need to validate your Quicken data file. It may have become damaged over time or as a result of the many crashes you had while running Quicken.
Please run this procedure, skipping no steps:
- Make a copy of your data file: Click File / File Operations / Copy.  Do not change any Copy Option settings. Save file under a new name in same folder as current Quicken data file.  (The Copy process appears to be performing a record-by-record copy of the data file and not just a simple binary image copy. This has been reported as recovering some otherwise not repairable files)
- Open the copied file in Quicken.
- Click File / File Operations / Validate and Repair. Click Validate File, check to make sure the copied file is being validated, click OK. Let it run.
- Fix any errors logged as not repaired by Quicken.
- Now close and restart Quicken using this new file and try your failing action again. If it works, keep using the new file and abandon the old one.
- If that doesn't resolve the issue, you may have no recourse but to restore your Quicken data file from a Manual or Automatic Backup taken prior to the problem first occurring, if necessary going back to older backups until you find a file that does not exhibit these symptoms.
