Hmm that window isn’t right at all so more has gone wrong than just the case open dialog being missing. Here’s what the top menu and toolbar should look like:
Did you at any time get a dialog about a jar being missing and chose to continue anyway?
Regardless, my suggestions would be:
- Go into AppData/Roaming and delete the “autopsy” folder. Note you should only do this if you have no settings you want to save - it will delete any keyword lists, ingest profiles, interesting file rules, etc. If you have settings you want saved, rename or move the Autopsy folder instead of deleting it
- Reinstall and see if the issue is resolved. If you want to restore your settings, replace the “autopy/config” folder in the new “autopsy” folder you’ll find in AppData with your saved version. Hopefully this won’t cause the problem to come back.
