Sorry, my bad, might be 97 running on windows 98 - but yes, this is a giant corporation serving hundreds of corporate customers and a few hundred thousand private ones, using nearly 30 years old software because the management does not see reasons to upgrade and spend the extra cost associated with it. New machines and Windows XP are only used by upper management.

Worst part?

Their whole software stack is running on some version of Visual Basic, written by a dude that did not trust "others code" so he wrote everything from scratch, and retired about 5 years ago.

Nobody knows how any of it works, or has any clue. The company will continue to run it and pay him for consultations as long as he is able to do it.
