File Is Deselected After Running Command

If I select a file in my lister:
The file is now outlined

And now run a custom dopus command, such as:
"C:\Program Files\MPC HomeCinema (x64)\mpc-hc64.exe" {f!}

the file is now deselected and looks like this:

How do I run my command while keeping the file selected the way it is in the first image?

Add a line with @nodeslect to the top of the command. (Click Advanced in the button editor if it's not in multi-line mode.)

Thanks, that did it!
