Jeff,

InterlockedCompareExchange64 is a 64-bit-only instruction.  Are you running XP 32-bit (I think you are b/c I don't think there was a XP64 SP3...).  You need the 32-bit OpenMPI version.  If you are running a 64-bit OS, but building a 32-bit executable, that instruction isn't available in 32-bit and you still need to link with 32-bit OpenMPI.

I'm having a problem using the prebuilt Windows version 1.5.3 with my app built with MS VisualStudio 2010.  I get an error message (for each node) that says: "The procedure entry point InterlockedCompareExchange64 could not be located in the dynamic link library KERNEL32.dll".  I'm running Windows XP, sp 3.
