For Office for Mac, you can have up to 25 licenses associated with the same Microsoft account: only one license for an Office 365 subscription and multiple one-time-use installs of Office for Mac Home and Student or Home and Business. If you have multiple Mac licenses associated with the same Microsoft account, it's best to start with an Office 365 subscription. A one-time-use license can not be deactivated. If you don’t have an Office 365 subscription, start by using the license at the top of the list and moving your way down. There isn't a way to track your one-time licenses so we recommend you keep a list as to which license is activated on which device. If you don’t remember which license was used, you'll have to go through a process of elimination to determine which ones you've used so far.

Microsoft on Tuesday released its new Office 2013 and Office 365 productivity software suites. Lost in the announcement, however, was what (if anything) those suites would mean to Mac users. Download adobe reader 10 for free.
