Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
Thank you for contacting Microsoft Community. As I understand you are not able to install the Office 2013.
The possible cause for the error 1406 during the installation of the program would be as follows:
- If file does not have sufficient permissions to modify sections of the registry that is required to perform the action. The permission for the Everyone group of the registry sub key noted in the error message is not set to Full Control.
- There is a third-party application on the computer that is denying the required access to the registry sub key.
You may try the below steps and check if it helps.
Step 1:
Start the computer in clean boot and try to install the Office suite:

Note: Ensure to restart the computer in normal mode once troubleshooting is completed
Clean boot is performed to disable all startup programs and 3rd party services on the machine and check if they are conflicting with the Office program.
Step 2:
If the above step fails, you may try giving the permission (full control) to the keys which prompt during the installation and check if it helps.
You may refer to the link below to know how to give permission to the keys:

(Refer to the section Assigning Permissions to a Registry Keyin the above link)
Ensure to take a back up of the registry before modifying it.
- Hold Windows key + R
- Copy and paste, or type the following command in the Open box, and then press Enter:
regedit
- In the registry window right click on Computer and click export to take a back up before giving the permission.
I hope the above steps helps. If you need further assistance on this particular issue or any other Office related issues let us know and we will be glad to assist you.
Thank you.
