Hi, 

if all you're after is launching nother application from within a Scratch
image, you might just take the BYOB image's SystemPlugin class and DLL. This
is a very simply OS app launcher that you can easily port into the Scratch
image by filing out the SystemPlugin class from BYOB and filing it into
Scratch. Be sure to also copy the DLL to your Scratch folder.

I created the SystemPlugin to enable BYOB to call the external
EXE/APP-Packer pseudo-compiler from within the image. Assuming that's
similar to what you're interested in this might probably be the easiest and
most straightforward way to go.
