So it looks what you need to do is install the LabVIEW Runtime Engine
and any needed drivers (DAQ, VISA, etc..) on each machine. This will
enable you to run your application.
There is no built-in update feature. This is something you will have to create yourself.
To force an update on your command, you'll need to build a "watcher"
service into your application so that when you initiate an update, the
individule applications can respond accordingly. (If no test is
currently running, update now - If test is running, update when
complete) Then you'll need an update application that can send the
updates to all the machines.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
