Hi,
Did you have installed other version Office before?
If yes, I suggest you check the the status of Office license in PC, maybe this problem is related to not completely uninstalling older versions of Office product keys, please follow these steps:
Search CMD, right-click the Command Prompt and run as administrator.
Then copy and paste the command, click Enter at last:
cscript.exe "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /dstatus
If you are running 32-bit Office on a 64-bit operating system:
cscript.exe "%ProgramFiles(x86)%\Microsoft Office\Office16\ospp.vbs" /dstatus
If you can find the older Office product key in list, try to remove it by typing the following command with the Last 5 characters of installed product key (I replace it with XXXXX, but what you type in is what you see on your computer) in this interface:
cscript.exe "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /unpkey:XXXXX
If the 32bit version of Office installed on a 64bit operation, run the following command:
cscript.exe "%ProgramFiles(x86)%\Microsoft Office\Office16\ospp.vbs" /unpkey:XXXXX
