JRE and JDK 64bit install executable are throwing a non compatible win32 error:

jre_7u1_windows-x64bit.exe is not a valid Win32 application.

I thought this could be a system environment variable problem, but from what I can tell it is not, the variable PROCESSOR_ARCHITECTURE is set as:


and the variable PROCESSOR_IDENTIFIER is set as:

Intel64 Family 6 Model 37 Stepping 5, GenuineIntel

I am not sure what variables the installer reads from if any.

I have tried java 6 installer and the same thing. I can install other programs designed for a 64bit architecture and I have looked at Control Panel>System and Security>System: which is in fact "System type: 64-bit Operating System".
