Yeah pretty much. Even if its only say 5% of your users cannot ever run your game, it means massive hassle in trying to manage orders/refunds/support, it means 5% less sales at face value on a commerical product, but when you get enough bad reviews of: "game wouldn't even start" it could hurt a lot more too. Thats not even to say its going to be 5%, could be more.
I have narrowed it down to not a dependency on VC++, .NET or Direct X runtimes, not a bad download, and not anti virus, so im stumped.
Here is the latest package if that is relevant:
