Redeem codes are used to deposit licenses in your User Area account. You just need to log in, go to the "Redeem" tab and paste the code in the text field.

Once done, a license for the product you purchased is deposited in your account and you'll be able to download the installers and the license file.

PLEASE NOTE: Redeem codes are only needed to be used once. After successfully deposited the license, the code will be voided.
