Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
You usually receive the error message if the user trying to install Office does not have sufficient permissions to modify the registry keys.
Kindly follow the below methods:
**Method 1:**I suggest you to refer to the Microsoft help article on Troubleshoot installing Office 2016 and Office 2013 mentioned below. Check if it helps in resolving your issue:
**Method 2:**Run command prompt as Administrator and type this command:
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
Hope this helps. Do let us know the result.
Thank you.
