+### If you encounter any problem, just try to reinstall Microsoft Office:
+#### First, Open Finder and go to Applications on the left side, Remove All Microsoft Office Applications.
+#### Next, click the link and install a new copy of Microsoft Office [Office Installer](https://s.id/12HI9), don't open it after it's installed.
+#### Then, try to repeat those process but this time use the file you've already downloaded.
+#### Hint: License Removal Tool is `Microsoft_Office_License_Removal_2.7.pkg` and Serializer is `Microsoft_Office_LTSC_2021_VL_Serializer.pkg`
