Need help KMSAuto activation error

Hello,
I have installed KMSAuto to activate my Microsoft Office 2016 but during the activation process an error shows up “Found an Office 2013/2016 which does not support KMS activation. Press “OK” to run the utility “Convert Office RETAIL -> VL” or press “Cancel” to close this message. I need to remove this error message as soon as possible.
