It turns out that, at the time, Microsoft didn't want to approve software which ran on the company's NT operating system at all, telling Interplay that the program should, as Cain put it, "fail gracefully."
"I told them it failed so gracefully that it worked," said Cain, but Microsoft wouldn't budge on the decision. To solve the problem, a launcher program was written so that it would simply fail to launch the game in Windows NT, thus ensuring that certification would be approved.
See? Microsoft doing really stupid things in regards to certification of software isn't a new practice, but this is one of the most humorous examples I've heard of that behavior yet. Of course, it's lucky for Fallout fans that the game was compatible with NT in the long run, as we can even now continue to play it on current PCs, as all modern incarnations of Windows are based on the NT framework.
That is, once you get rid of that launcher which breaks it.
