JRE and JDK 64bit install executable are throwing a non compatible win32 error: jre_7u1_windows-x64bit.exe

  • 0

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:

AMD64

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 the 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“.

    Most probably the file that you downloaded is corrupted. Check that it downloaded completely, or try to use another browser to download the installer. Unfortunately there are no checksums on the JRE download pages.

    Also check the digital signature is valid and shows no warning: open the properties dialog of the installer and then click Digital Signatures tab.
