Fix Microsoft Office Activation Error 0X4004F00C

Some Office users encounter the 0X4004F00C error when using a Microsoft Office suite product. This error is reported to occur at random times or when the user checks the product information window.

Each possible fix below assumes that your license key is valid. None of the following methods will work if you encounter this problem with an invalid/pirated license key.

Download the Office suite from the official Microsoft website

Step 1: Open your browser, type the following link in the address bar and press Enter:

Step 2: Scroll down and find the link to download the version of Office you are using.

For example, we’re using the MS Office 2016 version, so we clicked “Download” for it.

That’s it. That should fix your error. However, if that doesn’t work, try the second method.

Use the command line

  • Go to Office 16.

Now copy the path from the position bar.

Step 4: Go back to the command prompt window (administrator mode), type cd, press the space bar, and paste the copied path as follows. Press Enter:

Step 5: Now type the following command and press Enter again:

Step 7: Enter the following command and press Enter again:

Launch the Office activation tool

In fact, this activation sequence has already been mitigated by Microsoft. In fact, the tech giant has already released three different troubleshooting utilities that can automatically resolve the problem (one for each version of Office).

Each of these utilities provides a number of common troubleshooting steps that can be applied automatically when a detectable scenario is detected. If an investigation discovers an issue that is already covered by a fix strategy included in the fix, the utility automatically applies the recommended fix.

  • Download one of the following Office activation troubleshooting tools, depending on the version of Office you are using.
  • When the download is complete, open the .exe / .diagcab file and click Yes under Account Control to grant administrator rights.
  • If you are in the Office activation troubleshooter, first click the “Advanced” menu and check the “Apply fixes automatically” box. Then click Next to go to the next menu.
  • Wait for the first scan to complete and see if the application has been detected. If a fix is found that can be used, it is applied automatically. Depending on the type of fix, some steps may need to be performed automatically. If so, click Apply this update and follow the instructions on the screen.
  • After successfully applying the update, restart your computer and open Microsoft Office the next time you restart your system to see if the problem is resolved.

Disable Windows Firewall Protection

First, click the Start button on the taskbar or press the Windows key. It is available on the left side of the keyboard. Then select Control Panel and hover your mouse over it. This will take you to a new page. Now you can manually search or use the search bar to find the firewall log.

When you find it, select that option and go directly to the left pane of the screen. The power on or off is displayed there. Select it and go to the network location. Select it and move the Public network section next.

Now try setting up the Office 2016 or 2013 version. If that doesn’t work, move on to the next solution.

Hopefully this will solve the problem. You can use all the products however you want.
