If you are activating a legacy softkey license or possess a red USB license starting with T or L (like L100000) on this machine, see this article.
If you have been assigned a network license starting with T or L (like L100000), see the "Installing on the client machine" section of this article. If you are accessing a network license that contains a 5 digit number (22000-40999) see the "client" section of this article.
