There is a local database included with traccar, did you follow the quickstart guide, watch the video https://www.traccar.org/quick-start/? Do you have Java installed on your path?
Windows install https://www.traccar.org/windows/
I would recommend to use official installer:
Hello team,
I'm really happy to join the team. I've downloaded traccar ZIP and already decompressed it o my locahost folder.
But when I try to connect I got an error showing 'Can't use db : Unknown database 'traccar''.
Seems like the Traccar database in not included in the ZIP Folder. So can I know where to download the Traccar Database?
Kind regards
