1. Manual method
Time needed: 1 minute.
Manually activate your Office 365 using KMS client key.
Open command prompt as admin.
First, you need to open command prompt with admin rights, then follow the instruction below step by step. Just copy/paste the commands and do not forget to hit Enter in order to execute them.
Navigate to your Office folder.
If you install your Office in the ProgramFiles folder, the path will be “%ProgramFiles%\Microsoft Office\Office16” or “%ProgramFiles(x86)%\Microsoft Office\Office16”. It depends on the architecture of the Windows OS you are using. If you are not sure of this issue, don’t worry, just run both of the commands above. One of them will be not executed and an error message will be printed on the screen.
cd /d %ProgramFiles%\Microsoft Office\Office16
cd /d %ProgramFiles(x86)%\Microsoft Office\Office16
Convert your Office license to volume one if possible.
If your Office is got from Microsoft, this step is required. On the contrary, if you install Office from a Volume ISO file, this is optional so just skip it if you want.
for /f %x in ('dir /b ..\root\Licenses16\proplusvl_kms*.xrm-ms') do cscript ospp.vbs /inslic:"..\root\Licenses16\%x"
