Whenever I run GameSetup.exe, what pops up on my screen is a small, non-scrollable window that does not include all of the options (they're off the edge of the window). Apparently there must be a Save button that's also off-window, as my only option seems to be Close Window in the task bar, after which I find none of my changes took effect. Does anyone have a solution to this problem?

That did the trick. Thanks!
