I figured it out why on some installs/cab builds using the <directory\attract.exe> -c <directory> command does not always work. It is pretty simple. If there is a space in the directory name, the command fails. In one of my builds, the directory was 'c:\Attract Mode', with a space between 'Attract' and 'Mode'. In another build, it was just 'c:\AttractMode', with no space.
Flipped the builds back and forth removing the space in the directory name and then updating the shell command. Like clock work, it would fail with the space in the directory name, then work without the space in the directory name.
Give it a shot and see if you an replicate it.
