Does your app fail because it gets a null UUID?
My app needs to have a unique ID on each PC, because it is used in a licensing system
Can you rely on getting a unique ID on Windows? The documentation for Win32_ComputerSystemProduct.UUID says that a string of all zeros is returned when a UUID is not available. This suggests that you can't, but maybe in practice it is always available.
