I’m getting similar problems on vorpX0.9.1+win10+runtime0.8 . It seems vorpX doesn’t hook with games or rift. For games I tried Skyrim , GTA5 and WoW, nothing responded to any in-game hotkeys while vorpX is running. And destop viewer doesn’t hook with rift.
I tried switch betweeen runtime 0.7/0.8, reinstall vorpX, uninstall other applications that may overwrite system graphic settings, reinstall directX, reinstall graphic card driver… problem remains.
