DsicEx v0.3/v0.4 fails to open files that are read-only, due to requesting Read/Write access on the file

What steps will reproduce the problem?
1. dump Wii Sports disc that came with my old Wii
2. place ISO in a folder
3. set the folder to deny write access

What is the expected output?
C:\Documents and Settings\Compaq_Administrator\My Documents\My Downloads\DiscEX-
v0.4-cred>DiscEx.exe i:\temp\Readonlytest\RSPE01V1.iso

 Error: Can't open "i:\temp\Readonlytest\RSPE01V1.iso"

Please provide any additional information below.

I have attached a Process Monitor log in CSV format, of DiscEx, getting a 
ERROR_ACCESS_DENIED when it called CreateFile in order to get a handle on the 
file, because the dwDesiredAccess was set to (GENERIC_READ | GENERIC_WRITE)
