Hi Brittanie,
To help us narrow down the issue, I’d like to confirm the following things:
1. Where do you download the Office 2011 for Mac?
2. Could you provide us with a screenshot regarding the error message?
3. What does Microsoft Office 2011 student edition mean?
4. Which account do you use when signing in to Office applications?
5. I noticed that you said you have the product key, did you purchase it for using Office 2011 for Mac?
Thanks,
Dunk
