You don't need a redemption code. Just start one of the applications of your subscription plan and log in (help- sign In). Log in with your Adobe ID. That's it. At least that how it worked with me.

You will sign in with your Adobe ID and password. Then you install from the creative cloud application manager.

if you have purchased Lightroom 6, which is not the creative cloud plan, then you should have received an e-mail with your serial number.
