The product is now linked to your account and you’re ready to download and install. Click the three dots again, in the drop down menu click “My Library”.
In the left hand column, click “Ready to install”, your redeemed product will be listed here, with an “Install” link to click.
If you had a trial/demo version of a product already installed, you must uninstall that first. Otherwise it can cause an error saying you still only have a trial/demo version, despite redeeming a code for the full product.
