Wrong. USC title 17, section 117(a):
(a) Making of Additional Copy or Adaptation by Owner of Copy.--Notwithstanding the provisions of section 106, it is not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy or adaptation of that computer program provided:
(1) that such a new copy or adaptation is created as an essential step in the utilization of the computer program in conjunction with a machine and that it is used in no other manner, or
(2) that such new copy or adaptation is for archival purposes only and that all archival copies are destroyed in the event that continued possession of the computer program should cease to be rightful.
In other words, regardless of what commercial software companies might like you to believe, using a program does not require a copyright license.
