Report Windows 10 / ME 4 problem in Macro Express and Macro Express Pro Posted September 4 · Edited September 4 by Samrae Fixed a few typos. Added comment about Window Controls 1 hour ago, Cory said: I was wrong. MEP works fine in UWP apps. I've been doing my activations incorrectly. I apologize for the misinformation. No, you were not wrong. UWP programs do not follow long established standards for Windows programming. Hooks work but many hotkeys are blocked. I cannot launch a UWP .exe using the Program Launch command so I have to launch it from the menus. They do not use Alt key shortcuts. The is no File menu. They are very slow and require long delays. They do not support Window Controls. Because you prefer to use Window Controls your statement that macros do not not work with UWP programs is not incorrect. Specifically, in this case, your macro activated with Ctrl+Keypad 9 did not activate. Changing the hotkey to Ctrl+Shift+b worked. Working with UWP programs is tedious and frustrating. But, with effort, I have been able to get macros to work with them. Your mileage may vary.
