Robins right, download it online and install it then just enter your product key, I got a new Mac a few months ago and just did that, lots of companies are doing away install disks all together. Let me know if you need any help
A lot of the PC Compatible cd drives are not compatible with Mac, so check the specs before you arrange a meet up. It was already answered here, but your best bet is to download the trial version of Office onto your computer, then activate it with the code that you purchased.
There is a reason these new computers don't come with cd/dvd drives anymore. Because they aren't needed and almost everything can be downloaded now.
At shanerc..the mac air is apples way to introduce a laptop to the market that was very lightweight and extremely portable,they made it without an optical drive or a way to plug in a landline and made it wifi only. Other manufacturers aren't doing away with optical drives all together because they know people like to watch movies on their laptops and also there's still the option to download CDs that I person might still have so the optical drive is still very much needed and is still very important as an industry standard. The Mac air is so slender there's no space for an optical drive where other makers leave plenty of room for the necessary drive to work for consumers.
@toni b..your iPad isn't a laptop that's why,this thread references a mac air(laptop)..not any of apples other proprietory items so in your case no optical but there isnt a need for ms on that because it can be done with an app if you need that kind of functionality.
