Need to re-install Creative Suite 6 on a re-built MacBook Pro: I have the DesignStandard_CS6_LS16.dmg from initial download, do I simply double-click on the dmg to install? Will I need any keycodes?

Caseycork92 you double click the DMG to mount the disk image.  You will also need to enter your serial number for Creative Suite 6 for Macintosh.  You can find information on how to locate your serial number under your account at Find your serial number quickly - http://helpx.adobe.com/x-productkb/global/find-serial-number.html.
