Issues with installing Neo4J 1.9, with Java 1.7, on Windows 7

[Rodger]

Hello,

I've been fighting with installing Neo4j 1.9 and 1.8
(and making this post) for the past three hours!

Here is my environment:

Windows 7 Ultimate with java:
java version "1.7.0_15"
Java(TM) SE Runtime Environment (build 1.7.0_15-b03)
Java HotSpot(TM) Client VM (build 23.7-b01, mixed mode, sharing)


I've installed this java version, because it was required for Mysql
and Netbeans.
So, downgrading java is not an option since these other softwares much
work.

---

I created environment variables:
JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_15\bin
JRE_HOME=C:\Program Files (x86)\Java\jre7\bin

JAVA_PATH=C:\Program Files (x86)\Java\jdk1.7.0_15\bin


I set the path to look for the correct version of java and NEO4J.


Unzipped neo4j-community-1.9-windows.zip



Tried to run neo4j.bat, but got the error:
The system cannot find the path specified.


--------

grep -i "system cannot" *
- nothing.


--------

I did a number of searches on the error.
No clear solution.


---------------------------- NEO4J Version 1.8
----------------------------



Then, tried to install Neo4j version 1.8.

Go into base.bat
From:
set wrapperJarFilename=windows-service-wrapper-*.jar

to:
set wrapperJarFilename=windows-service-wrapper-4.jar


---


Set the path. Run neo4j.bat, but got:

Neo4j.bat

Unable to locate jvm.
Could not find HKLM\SOFTWARE\JavaSoft\Java Runtime Environment/
CurrentVersion entry in windows registry.

Search online,

Look at the file, neo4j.bat

rem Attempt finding JVM via registry
set keyName=HKLM\SOFTWARE\JavaSoft\Java Runtime Environment
set valueName=CurrentVersion

FOR /F "usebackq skip=2 tokens=3" %%a IN (`REG QUERY "%keyName%" /v

)

if "%javaVersion%" == "" (

have %JAVA_HOME% environment variable defined and pointing to a JRE
installation, or the registry key defined.
goto:eof

Look at the registry.
There is no such branch at all: HKLM\SOFTWARE\JavaSoft
!!!!

(HKEY_LOCAL_MACHINE)




However, in the registry, search for: "Java Runtime Environment"
Find:


HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime
Environment

With:
Name: Java6FamilyVersion, value: 1.6.0_43
Name: Java7FamilyVersion, value: 1.7.0_15


----


Searching the registry for:
1.6.0_43

mainly finds plugins, for the browser:

Java Plug-in 1.6.0_43


But there is also:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime
Environment\1.6.0_43

name: JavaHome
value: C:\Program Files (x86)\Java\jre6



C:\Program Files (x86)\Java\jre6\bin>java -version
java version "1.6.0_43"
Java(TM) SE Runtime Environment (build 1.6.0_43-b01)
Java HotSpot(TM) Client VM (build 20.14-b01, mixed mode, sharing)


C:\Program Files (x86)\Java\jre6\bin>file java*.*

java-rmi.exe: MS-DOS executable PE for MS Windows (console)

java.dll: MS-DOS executable PE for MS Windows (DLL) (GUI)

javaws.exe: MS-DOS executable PE for MS Windows (GUI) Intel

But no JDK/SDK for 1.6.

So, the question is:


How can I get NEO4J 1.9, or 1.8 to work with:

java version "1.7.0_15"



Thanks a lot!

Good one! That worked. Thanks!

The crazy thing is, I also watched that video.

 

These little gotchas really get you.

Rodger,

anything we can improve!
