How do I use a gesture to run a particular .exe?

I have an .exe in a folder. I would like to use lets say a B gesture to run that exe when I need to. How do I assign B to this .exe?

This is really basic I know but how is it done ?

I found

I create general action

add a gesture I made

add a command

select

run - run program

select a file .exe path

But it doesn't work. Do I need a particular argument defined?

I have dozens of gestures that run exe files. Are you sure you gesture is being received? Try using a test command such as OSD.
