This happens all the time at the hospital I work at. I'm constantly flummoxed by how behind the times software vendors consistently are. We're still stuck on XP for the foreseeable future because some of our vendors are still pushing updates that are totally incompatible with NT6 with no timeline for when it might work.
They've had half a decade to fix their software, and they just aren't doing it. I understand that Enterprise moves slowly, but you eventually reach a point of absurdity, as well.
