Hi,
I just installed neo4j on Windows 10 and tried to run movie database but it gives error. Version is 4.1.3
I could not understand what is wrong from logs.

Most likely reason is either db instance is still running or it has crashed and left the lock file behind.

Check if the process is still running. If not delete that store_lock file and start the process again.
