Can’t install language packs on office 2016


I try to install a language pack on Office 2016 , but the installation fail at beginning with this message :

Couldn't stream office.

Sorry we can't find a required file. Please check that the
installation source is reachable , then try again.

Error code : 30812-4 (2)

I have downloaded language pack from Microsoft website :

I've tried with different language packs and it's the same situation.

I have also reformatted my PC , I've installed again windows 10 and office 2016 , and after I've tried again to install the language packs , but still it's the same error.

What can I do ?

Thank you !

Office 2016 Language Accessory Packs need Internet connection to install fully. Please make sure that you have an active Internet connection and it does take some time for the language pack to be installed. Please be patient. And also make sure that you are installing only 32-bit or 64-bit components of Office and not both. Otherwise, you will run into other problems like listed here.
