Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
The following worked for me.
Follow the instruction from https://support.microsoft.com/en-au/office/use-the-office-offline-installer-f0a85fe7-118f-41cb-a791-d59cef96ad1c#OfficePlans=signinorgid .
In my case, office was 64bitbusiness and my installOfficeBusRet64.xml looks like
<Configuration>
<Add OfficeClientEdition="64">
<Product ID="O365BusinessRetail">
<Language ID="en-us" />
</Product>
</Add>
</Configuration>
And finally, download and install office from command prompt as mentioned by Microsoft.
c:\odt\setup.exe /download installOfficeBusRet64.xml &
c:\odt\setup.exe /configure installOfficeBusRet64.xml
