You say that as if it matters. It does not. Copyright is the exclusive right to copy; the exclusive right to create derivative works; and the exclusive right to distribute the copy or derivative work. 17 U.S.C. § 106.

Doing any of those without a license is software piracy. (Note, however, that once properly licensed software is on your storage device, copying it into RAM or otherwise copying it "as an essential step in the utilization of the computer program" is always permitted. 17 U.S.C. § 117.)
