office 365 university help

I bought office 365 the other day from best buy. I downloaded it and I used word just fine. but when I saved it to the desktop and tried to open the file, it says that I don't have office 365. I can open word and open the file from there, but I want to know why it says that I don't have it....also when it tells me that I don't have it, it gives me the option to say "i already have it" or something like that. when I click it, it tells me to enter the product key and I do. when it takes me to the page it takes me to, it says that I already used one of my installs. so any idea what's going on?

Did you get an installation disc?

Microsoft Office 365 that's what's wrong. Why Microsoft ever came up with that is beyond me. You should have bought a full copy of Office 2013 and saved yourself a lot of trouble.
