If you are trying to download an older version of Mac OS before Yosemite, you will get this error because the software is no longer available from Apple. You can pick up an install disk at an Apple Store or order it online.

Once it's installed, follow these steps: (1) Complete Installation: After downloading OS X Lion from the App Store or a disk, the system will guide you through the installation process. (2) Sign in using your Mac account: Enter the username and password of your local Mac account (the account you were using before installing OS X Lion). (3) Sign in with Your Apple ID (optional). (4) Configure the system (if it’s a fresh installation): You might be prompted to set up a new user account, agree to Apple’s terms and conditions and configure Wi-Fi, Time Zone and other basic settings.
