Use the "Run an Application" action; Enter the path to the application in the first field, and the command line parameters in the "With these parameters" field.
You should end up with
Run application '%windir%\System32\DisplaySwitch.exe' -with parameters '/external'
Thanks for the reply
This fails for some reason. aka running Windows 10
If I just put the path into the first field such as: C:\Windows\System32 or %windir%\System32 then test run takes me to that location but there is no visible DisplaySwitch.exe there. It is only visible when browsing to that location via explorer.
Additionally VoiceAttach browse to location of the .exe also not visible.
Extra parameters do no seem to execute this .exe with the many things I've tried.
Seems like it should just work aka C:\Program Files (x86)\SimXperience\Sim Commander 4\Commander4.exe
Sim commander opens and runs fine, why not DisplaySwitch.exe ?
I don't really know why I can't just use this line to run DisplaySwitch.exe. aka C:\Windows\System32\DisplaySwitch.exe
This does not actually run DisplaySwitch.exe from voiceattack for some reason. No problem clicking on DisplaySwitch.exe within the explorer browsers.
No problem running any of these commands from command prompt. There must be some switch I need for VoiceAttack to run this .exe for some reason I don't understand.
