The other day I launched an old game and got met with an error, something about directX9 and missing a redistributable file or something. Decided not to fuck with it.

Yesterday I launched it again to take a closer look at the error message to see if I could fix it. No error message, game booted without issues.

My confusion.

I got 12/20 and most of the ones I got wrong are the ones I was second guessing myself on.
