microsoft office 2016 pro plus found 1920 problem how to fixed related with network Service not have permission to install program.
In Windows Explorer:
Right Click on the folder OfficeSoftwareProtection Platform from C:\Program Files\Common Files\Microsoft Shared and Microsoft from C:Program data(hidden folder) Properties > Security > Edit > Add > Type Network Service > OK > Check the Full control box > Apply and OK.
In Registry Editor (regedit.exe):
Go to HKEY_CLASSES_ROOT\AppID registry >Right Click on the folder > Permissions > Add > TypeNETWORK SERVICE > OK > Check Full Control > Apply > OK
This worked for me and many others with the same problem, and took mere minutes to do.
