1. Use the Office Activation Troubleshooter

This fix is specific to the users who are facing the error 0x80041015 while trying to activate Office.

Microsoft has developed an Office Activation troubleshooter that specifically helps with errors that prevent users from activating their Office installations.

It works by checking the current activation status of your Microsoft Office installation. Once that has been determined, the troubleshooter will perform a series of diagnostic tests to identify the underlying problem.

After identifying the problem, it will list down the potential solutions and recommendations you can perform manually or fix the issue itself.

Here is how you can run it:

1. Close all the Office applications and download the troubleshooter from the official Microsoft website . You will need to select the correct version of Office you are trying to install.

Apply the fixes suggested by the troubleshooter and check if the issue is resolved.

3. Update Microsoft Office Click-to-Run

This is an official fix released by Microsoft for this specific Office error.

Updating Microsoft Office Click-to-Run will address known issues and vulnerabilities in the software. These updates also often include compatibility enhancements for new operating system updates, which can fix the problem at hand.

However, this fix requires you to access any Office program (for example Word) to proceed. That means if you cannot access Office components at all, you can move to the next method listed below. Alternatively, you can try booting into Safe Mode and launching any Office application there.

Follow these steps to proceed:

1. Launch any Office application and head over to the File tab located in the top left corner of the application window.
2. From there, head over to Account.
   
3. In the Account section, you will find an option to “Update Options” or “Update Now” (depending on the Office version you are using. Click on this option.
4. Choose Update Now from the dropdown. This will initiate the update process for Click-to-Run.
   
5. Wait for the update process to complete and once it’s done, restart your computer.

Hopefully, upon reboot, you will no longer face the error 0x80041015.

4. Temporarily Disable Antivirus

If you are using a third-party security program on your computer, there is a chance that it is conflicting with the Office processes, leading to the issue at hand.

To check if this is the case in your situation, we recommend temporarily disabling the antivirus and checking if that makes any difference. Simply right-click on the antivirus icon in the taskbar and choose Disable until the computer is restarted.

Once it is disabled, perform the action that was initially triggering the error. If the problem was being caused by the antivirus, this should fix it. In case it does, this might be a good time to switch to another, more reliable security program . You can also enable Windows Defender’s Virus & threat protection feature to help you safeguard your system from unwanted software and malware.

5. Install Office in Safe Mode

If you are facing an installation error, it might be because a background process or service is interfering with the Office installation process.

If you have quite a few background processes running actively, we recommend disabling them one by one using Task Manager. While you are at it, shut down any apps or programs you are currently using as well.

Once done, check if the problem is resolved.

If not, you can boot into Safe Mode and try installing Office there. This state launches Windows with a set of minimal drivers and programs, which can help determine if another process (most likely third-party programs) is causing the problem due to conflicts.

If you manage to proceed with the installation in Safe Mode, uninstall any recently installed programs as they might be leading to the issue.
