IROME55,

Are you talking about a 64 bit windows app attempting to COMM with the PLC?  If so it won't run on Win 7 64 bit, particularly if you are using the ECOM SDK.  The ECOM DLL is a native 32-bit DLL and requires it to be compiled as a x86 application on a Win 32 bit machine (ie XP 32-bit) and then it will run on Win 7 64 bit.  Also, it cannot be debugged in the Visual Studio IDE environment on a 64-bit machine.

I'm hoping Host E has a 64 bit SDK in the works.
