Microsoft Product Activation

Microsoft Windows OS and Microsoft Office that are provided by Computing Support require periodic registration. These products need to contact the UCI-KMS license server at least every 6 months to keep them activated. To re-activate, you will need to be on the UCI network and start one of the Office programs. If you are off campus or on the UCI wireless, this can be accomplished by starting the UCI VPN client and then opening one of the Office programs.

Manual Activation for Windows

If for some reason MS Office will not automatically activate, you will need to open a command prompt with administrative privileges and run a script inside the Microsoft Office install. Here's how.

NOTE: If you are off-campus, don't forget to connect the UCI VPN. If you don't have it installed, go to OIT's webpage to get it.

  1. Right-click on the Command Prompt icon and choose “Run as Administrator”
  2. Navigate to one of these paths, depending on your installed version.
    • Office 2013 → “C:\Program Files\Microsoft Office\Office15”
    • Office 2016 → “C:\Program Files\Microsoft Office\Office16”
    • If you are running the 32 bit version of Office on a 64 bit installation of Windows, the directory would be
      • Office 2016 32-bit → C:\Program Files (x86)\Microsoft Office\Office15“
      • Office 2016 64-bit → “C:\Program Files (x86)\Microsoft Office\Office16”
    • cd <one-of-the-above-paths>
  3. Type this command to activate office:
    • cscript ospp.vbs /act
  4. Office should be activated after that.

Manual Activation for Mac

You've activated but you're still being asked to activate, or you keep seeing messages for “Activate Office to Create and Edit” when you've already activated:

Quit the app. For example, if you're using Word, you'll go to the upper left corner of your screen and click Word > Quit Word.

Restart any Office app and the message should be gone.

If this is a constant issue, reset your credentials:

Open Spotlight by selecting the magnifying glass at the top right of your desktop.

Search for and open Keychain.

Type in Office and then delete the data license file.

Download and run this script.



From RT ticket 64721 Professor Michael Dillencourt encountered what appeared to be an unusual circumstance. From his reply on August 9, 2017:

  • When I typed the command cscript ospp.vbs /act, I got an error message to the affect that the specified product key had been blocked, and telling me the last 5 characters of the blocked product key. (97367)
  • I then typed cscript ospp.vbs /unpkey:97367, and it told me that the product key had been successfully uninstalled.
  • I then retyped the command cscript ospp.vbs /act
  • When I started Excel after that, a screen came up telling me that Office was being configured. Also, a popup came up in Excel saying that it was being blocked by another process. I exited Excel.
  • After Office was done configuring itself, I started up Excel again and under File/Account it said it was activated.
