Are you getting "Oops, something went wrong"? Have you recently enabled a VPN? If so, this might be the problem. Try turning the VPN off and see if that helps.
Please verify this:In Windows Control Panel / System / Advanced System Settings / Environment Variables ensure that both the TEMP and TMP variables point to a valid and existing folder, typically C:\Windows\Temp or C:\Users\your_username_here\AppData\Local\Temp If they point to an incorrect or non-existent folder or drive change both variables to an existing folder on C:\ (or create one) and reboot Windows.
If the folder exists … does your Windows User Account have proper access rights to this folder? If Quicken cannot create and use temporary files, all sorts of malfunctions will occur. If the Temp folder is full of junk, clean it out. Delete all files and subfolders within the Temp folder structure that Windows allows you to delete. You may have to skip a few that are actively in use.
Make sure that files in the Temp folder are NOT accessed by cloud backup software at all.
Make sure that JAVA is installed and running.
If you haven't already, I suggest you perform both parts of the clean uninstall and install Quicken: https://www.quicken.com/support/using-qcleanui-uninstall-quicken
Also, verify the Windows Internet Options have all Use SSL options unchecked and all Use TLS options checked on the Advanced tab.
If the issue persists, I suggest you boot Windows in safe mode and attempt to reproduce the issue. If the issue does not reproduce with Windows booted in safe mode, you should incrementally enable services and startup programs to determine the source of the interference.
billnyberg said: Thanks for this, unfortunately this didn't work. I did the clean uninstall according to the link you sent. Saving both files in one folder etc. Renamed the data files. Reinstalled Quicken. Still crashes. Verified the internet options. Booted into safe mode and it still crashes. I'm at a loss. May be time to throw in the towel....
