Can you save Microsoft office from one computer onto a flash drive and install it on another?

No, you cannot directly save Microsoft Office from one computer to a flash drive and install it on another. Microsoft Office is typically tied to a specific license and activation key, which means it needs to be properly installed using the original installation media or downloaded from your Microsoft account. If you want to install it on another computer, you should use the original installation method or download it again using your valid license.
