  1. Key can only be set once (if you try second key, exception will be thrown). The best place to call this method is from static constructor of your application's main class. Valid serial key has multiple groups of alphanumeric characters, separated with dashes.
  2. Serial numbers for these versions are emailed to you after you place an order or can be found in Autodesk Account. If you have physical media (a DVD or USB key) for a 2013 or earlier product, your serial number and product key will be printed on the label of the product packaging. Example of label from 2011 version.
  3. You might set up a job that initializes new volumes using automatic processing to minimize librarian intervention. Use manual processing for initializing volumes when you want to change a known, existing volume serial number to another volume serial number. Scan can be performed in manual mode only.

Enter the serial number for the edition you want to use. Click [Register License] button. Follow the dialogue instruction to complete the license registration. Once you complete the above steps, you can use the new edition.

I installed Office 2013 and put in the product key when it asked me to. After typing in the product key, it allowed me to use MS Word once. After I closed MS Word and went to reopen it the next day, it said the product key I entered was incorrect (maybe I typed it in incorrectly). It asked me to change it. I tried opening MS word and clicking File -> Account but was unable to change the product key from there.

I then went to control panel -> uninstall a program and then clicked on Office 2013 and clicked 'change' but it gave me no option to change the product key. So I decided to uninstall and reinstall it.

I uninstalled it and then went to reinstall it with the setup file and now it is giving me an error saying:

The first product key I entered seems to be saved somewhere. How do I delete / change it?

Depending on the combination of Office 2013 and Window version you might have to change the path to Program Files(x86)

Here is the sequence that should work for (x64 Windows -> x64 Office) and (x86 Windows -> x86 Office):

  1. Open cmd prompt

  2. Run the following commands:

cscript 'C:Program FilesMicrosoft OfficeOffice15ospp.vbs' /dstatus

Note down the partial product key(s) (there can be multiple)

cscript 'C:Program FilesMicrosoft OfficeOffice15ospp.vbs' /unpkey:partial_key

This will uninstall an installed product key with partial product key you noted earlier. Uninstall all of the keys.

Now you should be able to add it from Control Panel the usual way. Or you can use:

cscript 'C:Program FilesMicrosoft OfficeOffice15ospp.vbs' /inpkey:new_full_key

Then you need to activate it.

cscript 'C:Program FilesMicrosoft OfficeOffice15ospp.vbs' /act

Just for update: Still works in Office 2016, you just need to change 'Office15' to 'Office16'.


Just run the setup for Office 2013 again and choose the option 'Enter a Product Key' in the first screen.
