See this thread.
Instead of leaving a bulleted process to follow, which amounts to the average user spending hours of frustration with trial and error, and then maybe giving up altogether, would it not be easier to leave a sample file, or put an example on your start page, so everyone could download, digest and learn from.
After all, you are trying to promote your own software, and the average user, beginner / novice, would not find your aforementioned process straightforward, because we are only talking about just sharing a screenshot, from a game, which is commonplace for a lot of games out on the market now.
