It seems that the issue I had with X5 is now showing up in X9 as well. See my post and "solution for now" from a couple of weeks ago.   I haven't attempted to return to X5 64-bit because I have work to turn out and X5 32-bit has not failed to launch since I installed it.   https://chieftalk.chiefarchitect.com/topic/15024-x5-and-windows-10-pro/
