Online Simulator Problem

Im using OMRON CX Programmer 7.2c
My PLC is CP1H
My OS is Windows 7 64 Bit
Everytime I try to simulate my work online, it says failed to connect to PLC.

There should not be an error since im just simulating it and when simulating, no plc should really be connected.

Please Help. Thanks in Advance

CX-Programmer is not yet compatible with Windows 7 - it will be shortly - probably late this year/early next year.
NO Omron software will run successfully on a 64 bit operating system. The comms problems you have encountered will also happen when trying to connect to a PLC. 64 bit is not really useful in industrial systems. You could try compatabilty mode but I do not believe it will work in real life.

Thanks a lot! compatibility mode works for the online simulator. That helps a lot since I have a deadline on school for my program
