System.BadImageFormatException on PC running PC Sim software

I'm getting this exception: System.BadImageFormatException was unhandled whenever I try to run a program compiled on my PC. I'm running the Okuma PC Sim software on my laptop.
This happens even if I open and compile the API Test app that ships with the API.
Below are the exception details:

System.BadImageFormatException was unhandled
  Message= is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

Long KB short... change your compile settings in VS. The "ANYCPU" setting should be changed to match the target system, x86 or x64.
