DataModeler 4.0 will not boot with the proper Java version.

Question

I have downloaded datamodeler 4.0.0.825-no-jre.zip to use the 64bit edition on my Windows 7 PC.  While 3.3 (also 64-bit) works just fine and I have not modified any of its configuration files, regardless of what configuration file I modified for DataModeleler 4.0, the first dialog indicates a failure with "Unable to launch the java Virtual Machine Located at path:  C:\Program Files (x86)\Java\jdk1.6.0_35\bin\msvcr71.dll".  This reference is made regardless if I double click from the Windows explorer or invoke Datamodeler 4.0 from the command line.  I use Powershell 3 when doing command line work.
When at the command line I run "java -version" and the right version is referenced Java version "1.7.0_09".
I look at my environmental variables (Workspace is identified by $Env: by Powershell), The word "Java" was not specified for any path:
($Env:Path).Split(';') | Where {$_.Value -match '(Java)'}
I did see that the 32bit path was specified as an source with the CLASSPATH veriable:
($Env:ClassPath).Split(';')
C:\Program Files (x86)\QuickTime\QTSystem\QTJava.zip
C:\Program Files\IBM\RationalSDLC\ClearQuest\cqjni.jar
So I added "C:\Program Files\Java\jdk1.7.0_09" to the environment using the command line to pick up that java version.  Verifying my effort:
($Env:ClassPath).Split(';')
C:\Program Files\Java\jdk1.7.0_09
C:\Program Files (x86)\QuickTime\QTSystem\QTJava.zip
C:\Program Files\IBM\RationalSDLC\ClearQuest\cqjni.jar
I also have edited the datamodeler64.conf and the datamodeler-Darwin.conf to both reference the desired Java version.
#SetJavaHome ../../jdk
SetJavaHome "C:\Program Files\Java\jdk1.7.0_09"
and
SetJavaHome /System/Library/Frameworks/javaVM.framework/Versions/1.7.0/Home  (I tried 1.7.0 and 1.7.0_09)
#SetJavaHome /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
I don't know quite where to go from here.  Everything I have tried fails and somehow the 32-bit 1.6 Java reference persists.  I even went to the Windows Registry trying to find it there, but failed.  It there another place or configuration file to modify or strategy to try?  Thank you for

Hi,
I also have edited the datamodeler64.conf and the datamodeler-Darwin.conf to both reference the desired Java version.
With Data Modeler version 4.0.0.825 on Windows 7, the file that identifies the JDK is C:\Users\<username>\AppData\Roaming\Oracle SQL Developer Data Modeler\4.0.0.825\product.conf
However, I would recommend you take Ivan's advice and download the production version (4.0.0.833) rather than continue with the Early Adopter version 4.0.0.825.
