I don't see why not. Just copy the files of the installation disc to a folder on the USB stick.
I always download Cross updates to my home PC then transfer the file via a USB stick to my gig laptop. It works for me

I do the same for my sound card and controller driver updates.
My gig laptop very rarely goes online, only to get updates for my OS.
