Can't start cq5 service under windows 7 64bit - service

Question

One year ago I installed successfully CQ5 as a windows service under Windows 7 32bit. After that I've switched to Windows 7 64bit. Currently I have a project using CQ5 so I install again it (under Window 64bit). CQ5 starts fine with crx-quickstart/bin/start.bat using command line. Also I don't see any problem when installing as service with the command instsrv.bat cq5:
Installing service cq5
runs in E:\servers\cq5-server\author\crx-quickstart
uses E:\servers\cq5-server\author\crx-quickstart\opt\helpers\\..\..\app\cq-quickstart-5.5.0-standalone.jar
starts org.apache.sling.launchpad.app.Main
redirects output to: E:\servers\cq5-server\author\crx-quickstart\logs\startup.log
But when I run net start cq5, I get an error as below:
The cq5 service is starting.
The cq5 service could not be started.
A service specific error occurred: 0.
More help is available by typing NET HELPMSG 3547.
And checking log file commons-daemon.2013-09-01.log, I see:

Could anyone let me know what I'm wrong?
I'm following the instructions at Installing and Starting Adobe Experience Manager as a Windows Service

Answer 1

I've set up JDK by copying java folder from another computer and setting the environment variable JAVA_HOME. So maybe something is missing in registry.
Below is how to fix the problem:
First follow correctly the first 3 steps in the instructions at Installing and Starting Adobe Experience Manager as a Windows Service. (In my case, I used prunsrv_amd64 to replace prunsrv)
Edit again the bat file instsrv.bat by changing
:: path to a jvm.dll or "auto"
set jvm_path="auto"
to
:: path to a jvm.dll or "auto"
set jvm_path="%JAVA_HOME%\jre\bin\server\jvm.dll"
Finally run instsrv.bat CQ5 under \crx-quickstart\opt\helpers
P/S: This way also does help in case of Windows XP 32bit (I've tested)!

Answer 2

You need to modify the instsrv script to use the 64 bit prunsrv.exe. You'll just want to open up the script and change all prunsrv commands to prunsrv_amd64 or prunsrv_ia64.
