Gephi & Windows 7 x64

[DCGump]

I am having trouble getting Gephi to work with my company's install of Windows 7. Via the start menu absolutely nothing happens. When I try to run the application from the command prompt, I get the following error message:

C:\Program Files (x86)\Gephi-0.8.2\bin>gephi.exe

C:\Program Files (x86)\Gephi-0.8.2\bin>

The launcher has determined that the parent process has a console and will reuse
it for its own console output.
Closing the console will result in termination of the running program.
Use '--console suppress' to suppress console output.
Use '--console new' to create a separate console window.

I have looked through the forum and found the "fix" for java under windows 7 and applied it as so in the gephi.conf file:

...
# default location of JDK/JRE, can be overridden by using --jdkhome <dir> switch

jdkhome="C:\Program Files (x86)\Java\jre7"
...


However, still no joy. I am running Java 7 update 55

Any help would be appreciated.
