Office KMS host setup error "0xC004F050 The software licensing service reported that the product key is invalid"


If you are attempting to set up an Office 2010 or Office 2013 KMS host by using the slmgr.vbs script, the “/ipk” switch, and a valid Office KMS host product key, the following error will occur:

Error: 0xC004F050 The software licensing service reported that the product key is invalid

Unlike Windows KMS host setup, Office KMS host setup involves installing a separate “KMS host license pack”, entering a related product key, and activating online or via phone.
