I hope this doesn't get posted twice. I accidently blew this away the first time.
Windows 11 Pro, Version 23H2, build 22631.3880
It started a few weeks ago. Sometimes I get the "Unable to initialize runtime components…" message and and sometimes I just get the "Quicken crash report" dialog. I've tried the various uninstall/reinstall and restart windows options with the same results. I can run Quicken on my test PC (not the best option) with the same data file I have tried on the crashing PC. I have tried the CTRL key, run as administrator option. In this case a blank Quicken window opens but if I select any menu item Quicken crashes with the crash report dialog.
I have run the validate file option on the data file which flags a few minor errors. I did not tick either of the other two options in the validate dialog.
I did a complete bare metal install of Windows 11 and ran all the updates. I then installed Quicken and it crashes as described above.
