ERROR: Could not open HEX file"

I have run into a problem with the hex2bin.exe utility. With the hex output file from uVision2, in HEX-80 format(only option I have), I am not able to create a binary file using the hex2bin utility.

The error I get is "ERROR: Could not open HEX file". Since the documentation on the hex2bin utility is so limited I can not determine what the problem is.

Thank you in advance for your ideas/thoughts.
