Okay, I installed PowerShell 5 and Java, and still have the error:

I can't get where the "java version 1.8.0_40" from. Please, help, somebody. Thanks!

Hello @k.my and welcome to the Neo4j community :slight_smile:

First, you should use Windows 10.
Did you try to install a database with Neo4j Desktop, it's better to use it especially to install a local database.

Thanks but there is no possibility for me to use windows 10.
I didn't try desktop as I don't know about it.

if you use win 7 , you need modify the file "neo4j.ps1" in bin path

modify the line
Import-Module "$PSScriptRoot\bin\Neo4j-Management.psd1"
to
Import-Module "your installation dir"\bin\Neo4j-Management.psd1"

For v4.2.6 - in case, encountered win10 powershell security issues, update file neo4j-enterprise-4.2.6\bin\neo4j.ps1 - adjust try block with following - this should work

try
{
Unblock-File -Path '$PSScriptRoot\Neo4j-Management*.*' -ErrorAction 'SilentlyContinue'
Unblock-File -Path '$PSScriptRoot\Neo4j-Management.psd1' -ErrorAction 'SilentlyContinue'
}
catch
{
};

Import-Module "$PSScriptRoot\Neo4j-Management.psd1"

if Neo4J as a service, underlying win environment doesn't support - run with standalone

neo4j.bat console -verbose
