System: Windows 10 1709 Professional (x64) Office Pro Plus 2016 (x64) I try to update Office 2016 using DISM, but cannot make it work. I am using .cab update file What i did: 1. Used link from WUMT to download the cab file (cannot post the link - forum rules) 2. Renamed the cab file to ABC.cab (for testing) and put it inside C drive "c:\ABC.cab" 3. Run cmd as admin 4. dism /online /add-package /packagepath:c:ABC.cab dism /online /add-package /packagepath:c:\ABC.cab dism /online /add-package /packagepath:"c:\ABC.cab" All of them give error The reason i want to use DISM method is I want to update Office 2016 on computer which doesn't have internet access Do i make something wrong on DISM syntax or Is there any other method. If DISM can work, then is it possible to update all the update-files by putting in one folder and used only one dism command.
