Unfortunately, the Windows Store edition can only support 1 command-line tool which must be a command-line executable.
You can run any process without a command-line window using a custom launcher that passes the appropriate flags, e.g. using Python like so:

If you're using the amc script then this dedicated Python launcher may work better for you:
https://github.com/filebot/plugins/blob ... rocess.pyw
