Hi Jerome!
As did, tst, I would guess that you are calling subVIs dynamically in your top-level VI. You will need to manually include each of your VIs that you call dynamically. To do so, under the Support Files, you'll see that one of the buttons is Add Dynamic VI.
Also, make sure you have the same drivers installed on your other computer. For example, if your VI includes NI-DAQ programming, you will need to have NI-DAQ installed on the other PC!
Hope this helps!
