I have just had this problem. I noticed that where you provide the location of IFOEdit that the file wasn't displayed in the directory hwere it was located. This was beacuse, either I had renamed the different versions as ifoedit95.exe & ifoedit96.exe for clarity, or they may have been downloaded like that (?). When I renamed the program to ifoedit.exe and ensured clear dircetories in all of the paths it worked fine.
