For neo4j community edition on windows，Failed to start Neo4j with an older data store version

Question

I use the neo4j community edition on windows to see a database. The path of database is D:\Alamgir\neo4jdb. When start it shows:

Failed to start Neo4j with an older data store version.
To enable automatic upgrade, please set configuration parameter "allow_store_upgrade=true"

I update the parameter on neo4j.properties and neo4j.conf just like this:

But it still doesn't work .What can I do? Help~

So did you uncomment the line ? Also what version of neo4j are you running ? — Christophe Willemsen

You need to uncomment the line in the config file, i.e. remove the preceding #:

allow_store_upgrade=true
