How can I install a pc program on another pc other than a flash drive?

I have a recording program called cubase and some buddies of mine need the program to record n edit there music. Thng is I can't find the original install disk n I don't have a flash drive large enough to put a copy of the program on. I'm pretty sure there's a simple way to do it but I can't lie I'm not all that pc literate any help would be MUCH apreciated
