Watlow EZ-Zone Instrument Driver Readme.HTML  I wonder why they named it that???

NOTE: When using Serial or USB communications, it is required that the following dll’s are placed in the same location as the executable.

• SerialLink.dll
• SerialLink64.dll
• UsbLink.dll
• UsbLink64.dll

Thanks for the respond guys.  I didn't copy those dll because I was using Ethernet instead of serial/usb.  However since you mentioned it, I copy all the dlls and tested the program.  It worked! 

The missing dll is actually the Usblink.dll.
