my IT manager at work (1200mi away) gave me a product key for Office 2013. when I click on the icon on my Surface Pro 2 for MS office it give three options, Buy it, Activate it, Try it....of course i select Activate It, and it then prompts me to enter a prodcut key. which i then enter what my IT manager gave me. When I do this, it give me the following message, "This product key is for teh volume-licenced version of Microsoft Office Standard 2013, which isn't currently installed. To use this product key, contract your administrator." I assume I need to install Office 2013 standard before I can use this key, correct? If thats correct, whats the easiest way to install it?
