I had a client purchase 5 copies of Microsoft Office 2013 from a local big box store. The license comes on a card that has to be entered into a office.com account to retrieve the CD Key. On Office.com however, there is no way to tell them apart. Because of this confusion the same key was used on multiple machines, while other keys weren’t used at all.
One computer at this clients office was unable to activate office because the license key had been activated multiple times already. I needed to change the key that on that computer. Microsoft has changed the way that keys are hendled with office 2013. With this version, you must use a command line utility to change the key. The key “7HE3G-HE84N-JCU44-JJGN4-QQU447” is just a random string formatted like a real key for illustration purposes. Replace that with your real CD Key. Also note that the key on the back of the card is not the CD key. To obtain the real CD key, follow these directions.
For 32 bit Windows:
cscript “C:\Program Files\Microsoft Office\Office15\OSPP.VBS” /inpkey:7HE3G-HE84N-JCU44-JJGN4-QQU447
For 64 bit Windows (assuming you are using 32 bit Office):
cscript “C:\Program Files (x86)\Microsoft Office\Office15\OSPP.VBS” /inpkey:7HE3G-HE84N-JCU44-JJGN4-QQU447
The Kaseya audit dosen’t show license key information for Office 2013, so I just had to guess which license was meant for which machine.
