Open application instance

[Kamocat]

I'd like to use scripting to open up a VI in a different application instance.

My entire goal is to make a VI to change all my open VIs (or all my open VIs within a certain directory) to be targeted to my Lego Mindstorms NXT, so that my revision control doesn't try to record the recompile that results when I switch between targeting my computer and targeting the NXT.

Anyways, I'm a little confused about how to go about this.  LabVIEW crashes when I try to get the operating system info of a VI targeted to the NXT.

So, I had put that aside and was trying to figure out how to switch a VI between the application instance of the Project and the main application instance.

Let's start with the basics:
How do I create an application instance that is different than the current one?

How do I open up an already open VI in a new application instance?  (Do I need to save it first and then call it by path?)
