I have attempted to run Autopsy several times, and keep getting the above error message. I have uninstalled and reinstalled several times, always getting the same message. Any and all help is tremendously appreciated. Thanks!
If you disable the Keyword Search ingest module, can you ingest a data source?
It might help to see your logs. Go to Help->Open Log Folder and see if there are any stack traces or errors relating to solr/keyword search.
