I too am experiencing _keycode192 I've done everything you said but when I start VoiceAttack I get the following message; Stopped command, 'F_init' : focus lost.
My os is windows 10 pro, VA is running in Admin and compatible mode windows 7, I even tried 8, I tried giving VA folder special permissions. I do however get this message Shortcut : 'F_interruptKey' as I am typing this post. Saying Squad does nothing but give me that error message Release by variable [_keyCode192] not set. No keys released. Key down by variable [_keyCode192] not set. No keys pressed. So what do I do now?
