How to change the saved Office 2013 Product Key - Super User most recent 30 from 2019-06-20T15:30:59Z 6 How to change the saved Office 2013 Product Key user2719875 2014-05-28T00:18:35Z 2015-11-15T00:02:53Z <p>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.</p> <p>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.</p> <p>I uninstalled it and then went to reinstall it with the setup file and now it is giving me an error saying:</p> <pre><code>Error 25004. The product key you entered cannot be used on this machine. This is most likely due to previous Office 2013 trials being installed. </code></pre> <p>The first product key I entered seems to be saved somewhere. How do I delete / change it?</p> 16 Answer by balwa for How to change the saved Office 2013 Product Key balwa 2014-05-28T00:58:43Z 2015-10-07T23:14:46Z <p>Depending on the combination of Office 2013 and Window version you might have to change the path to Program Files(x86)</p> <p>Here is the sequence that should work for (x64 Windows -> x64 Office) and (x86 Windows -> x86 Office):</p> <ol> <li><p>Open cmd prompt</p></li> <li><p>Run the following commands:</p></li> </ol> <blockquote> <p>cscript "C:\Program Files\Microsoft Office\Office15\ospp.vbs" /dstatus</p> </blockquote> <p>Note down the partial product key(s) (there can be multiple)</p> <blockquote> <p>cscript "C:\Program Files\Microsoft Office\Office15\ospp.vbs" /unpkey:partial_key</p> </blockquote> <p>This will uninstall an installed product key with partial product key you noted earlier. Uninstall all of the keys.</p> <p>Now you should be able to add it from Control Panel the usual way. Or you can use:</p> <blockquote> <p>cscript "C:\Program Files\Microsoft Office\Office15\ospp.vbs" /inpkey:new_full_key</p> </blockquote> <p>Then you need to activate it. </p> <blockquote> <p>cscript "C:\Program Files\Microsoft Office\Office15\ospp.vbs" /act</p> </blockquote> <p>Just for update: Still works in Office 2016, you just need to change "Office15" to "Office16".</p> 2 Answer by Tudor Olariu for How to change the saved Office 2013 Product Key Tudor Olariu 2014-12-04T13:35:35Z 2014-12-04T13:35:35Z <p>Just run the setup for Office 2013 again and choose the option "Enter a Product Key" in the first screen.</p>
