If you are getting GET GENUINE OFFICE. I suggest you try this
Open Command Prompt and Run it as Admin.
reg delete “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform” /f /v KeyManagementServiceName
reg delete “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OfficeSoftwareProtectionPlatform” /f /v KeyManagementServiceName
If above doesn’t work use this other method in Command Prompt.
cd C:\Program Files\Microsoft Office\Office16
cscript ospp.vbs /sethst:193.29.63.133
cscript ospp.vbs /act
