Targeting can be performed either by window title, process name, or window class.
If your target application is running, and uses a standard window, it should appear in that list by its window title, provided the "Command Multi-Edit" window was opened while the application was already running.
The name of the process will normally be the same as that of the executable, and can be typed in manually. The location of the executable is irrelevant to targeting.
Note that the "Processes" tab of Windows task manager does not show process names. The "Details" tab does, though with a ".exe" suffix, which is not actually part of the process name.
However, under normal circumstances, sending input to the active window should work, as long as your target application actually has focus.
As mentioned in
this topic, you may need to run VoiceAttack as administrator (though this is normally only required if the target application is running as administrator), or increase the duration keys are held down for before being released.
