Microsoft Office Licensing

 New Activation Method

Instead of requiring individual activation keys, Microsoft Windows and Microsoft Office are now activated through the Key Management Service. Technical support providers will find information on our KMS page.


Under the Campus Agreement, Cornell University staff, faculty, and affiliates can download Microsoft Office to install onto their Cornell-owned computers at no charge.

The site license only covers installation of Office onto computers owned by Cornell University or its affiliated institutions*. 

Please note that Weill Cornell Medical College has its own arrangement with Microsoft, and is not covered by the Campus Agreement.  Weill Cornell staff and faculty should check with their local IT providers for more information.

Older Versions of Office

While a selection of earlier versions of Office for Windows and Macintosh are covered by our license, we strongly advise only using the current release. Please check with your local IT staff to find out if you have a specific need for an earlier version of Office. If you truly have a need to use an earlier release of Office, please send us a request via e-mail.

Note on file format:  Microsoft Office installers are distributed as ISO files, an industry-standard disk image format.  For more information on using this file type, please see our How To Work With ISO Files online guide.

Product Activation

Our Office Professional Plus installers are configured to use the KMS automated activation system. Office should activate automatically as soon as your machine connects to the Internet via an on-campus local area network, including the RedRover or RedRover Secure wireless network. All Cornell local area networks provided by CIT, and most networks provided by local IT providers are configured for KMS.  If you are on a local area network that isn't configured for KMS, you can activate via KMS manually by following our online instructions

If you need to activate Office Professional Plus on a computer that cannot connect to our KMS server, such as for a computer that will not be connected to the Internet, please contact us to request an MAK product key. Please include the reason why KMS isn't appropriate for your situation.

Microsoft Office Home Use Program

Cornell employees can purchase a Home Use license for $9.95.  The Home Use Program (HUP) currently allows purchase of one license of the current release of Office Professional Plus for Windows or Office Standard for Macintosh. Office suites purchased under the Home Use Program can be used for non-work-related use and also by other members of the employee's household. You will need our Microsoft Home Use Program Code to register.

You must use your Cornell University e-mail address to register for the Home Use Program. If you try to register with a non-Cornell address, you will not be able to register.

After your purchase is complete, the vendor will send you a link to download the HUP version of the Office installer of your choice (Mac or Windows) and a personalized Product Key. The installer and Product Key are provided directly from the vendor to you. We recommend that you make or purchase a backup copy of the installer, and keep a hard copy of your Product Key for your records.

Home Use Program Support

The Microsoft Home Use Program is not a service of Cornell University. The online retailer Digital River LLC manages the Microsoft Home Use Program. The program is available to employees of any institution with a Microsoft Office site license (such as Cornell University).

CU Software cannot replace a lost installer or Product Key. If you lose your installer or Product Key, have questions about the program, or need any other help with the Home Use Program, please refer to Digital River customer support, at:

The current releases available from the Home Use Program are Office Professional Plus 2013 for Windows, and Office Standard 2011 for Macintosh.

Other Office Products

Office Language Packs are available under the Campus Agreement at no charge upon request.  Contact us by e-mail and request which specific language pack(s) you need, and we'll make them available and send you links to download them.  Each pack is about 500 MB in size. Please notes that Microsoft does not offer Language Packs for Office Standard for Macintosh.

Office applications that are not part of the Professional Plus suite, such as Project and Visio, are not currently covered by the Campus Agreement, and are not available for free.  You can purchase Project or Visio at a large discount through the Microsoft Select Program.
