Help and Tutorials

Common Questions

Office repeatedly prompts me to activate on a new PC?

Please follow the instructions at to update your registry.  This is an intermittent problem with Office.

Why am I being prompted for a product or activation key?

You must uninstall all previous versions (trial versions and full versions) of Office and the Get Office app (if present) before you download and install UB's version.

If you did, re-start your computer and launch the software again.

If you did, and still get prompted for a key, run the Office Easy Fix Removal Tool to remove any remnants of Office that may still be on your computer, then install UB's version. 

If I delete a previous version of Office, do my files get deleted?

No, deleting old versions of office does not delete or harm files you produced using Office.

May I download Office more than once?


Can I use Office on a Mac?

Yes. You can download Office 2019 for Mac. Additionally, If you are using a Macintosh computer running Boot Camp or running Parallels or VMWare and your computer meets the requirements, you can run Office 2019 for Windows on your Mac.

Can I order a physical copy of Office media?


How can I log into OneNote online after I install Office?

Go to and create a free Microsoft account.

How can I use Word with languages other than English?

See the Microsoft page for Enabling Other Languages.

How long can I use Office?

Your Office download will continue to work the entire time you are at UB. When you are no longer a current student, faculty or staff member, you must remove Office from your computer.
