To solve the problem of denial of access to the Office installation source

Disable firewall malfunction

In most cases, the connection between your local Office applications and external servers is lost due to false alarms caused by redundant protections.

A number of third-party applications have been known to cause this problem with false positives. Komodo and McAfee are examples of third-party apps that can cause this problem. If you suspect that one of these apps is the source, you may want to turn off real-time protection.

However, you can usually deactivate real-time protection directly from the task bar menu, depending on which security package you use.

Move File Failed Code 5

While SeeYou is running in the background, you may experience this issue when you run a new installation file.

Even if you disable real-time protection, the security rules will likely remain in place if you’re using a third-party tool with a firewall. As a result, your firewall settings must be modified to whitelist desktop connections (depending on your security tool).

This can be done easily if your VA makes it difficult to create exceptions. Simply delete the file and the remaining files (at least until your license is activated).

  1. The “Programs and Features” menu can be accessed by pressing Windows + R and typing “appwiz.cpl” into the “Run” dialog box.
  2. The third-party security package you want to uninstall can be found by scrolling through the list of installed applications under the “Programs and Features” menu.
  3. Follow the instructions on the screen to uninstall the third-party security package when you see it by right-clicking and selecting Uninstall on the context menu.
  4. You can check if the problem is resolved by restarting your computer after the process is complete.
  5. Ensure that all remaining files have been deleted by following this article (here).
  6. Fill out the application again in the Office program.

You may try the next method below if you are still receiving error code 0x4004f00d.

Disable VPN / proxy interference

A proxy server or a VPN client that establishes a private network connection tends to crash office applications when they work with it. It works most of the time, but it tends to produce errors if it’s time to perform sensitive tasks.

Activation error code 0x4004f00d most likely occurs when the VPN client or proxy server is disabled before running Office applications. If this is the case, you can remove the proxy client (or VPN client) before running Office.

Shellexecuteex Failed Code 5

In addition, a corrupted system account or active directory can result in the Error 5: Access is denied message. You can solve such problems by restoring Windows to an earlier date.

As well as preventing PC problems, this tool helps you optimize your computer for maximum performance. In addition, it is a great tool for protecting you against file loss and malware. Using the program, you will be able to resolve common Windows errors quickly and easily, without having to spend hours troubleshooting:

Using a VPN client requires a different set of instructions than proxy users. We have created two different guides to assist you:

The proxy server needs to be disabled

  1. Open the Settings application by pressing the Windows + R keys and typing “ms-settings:network-proxy” in the text box. Press Enter to open the Proxy tab.
  2. You can uncheck “Use a proxy server” under the Manual Proxy Configuration tab on the Proxy tab.
  3. Check if the activation error has now been corrected by restarting your computer and repeating the action that caused it.

Client uninstallation

  1. Using Windows + R, open the Run dialog box. Type “appwiz.cpl” and hit Enter. Click “Yes” when prompted for User Account Control (UAC).
  2. When you see the third-party VPN in the Programs and Features window, right-click on it, choose Uninstall from the context menu, and then restart your computer.
  3. If you are still experiencing problems after restarting your computer, try following the instructions in the uninstall wizard.

Activation error 0x4004f00d may also be caused by a combination of the following factors, so proceed to the next solution if this one did not fix the problem.

Deleting the MS Office

Apparently, a failure to update or an interruption to the machine can also cause this problem. This is related to a corruption in the Authority structure.

A simple solution is to uninstall the Office installation and run the “Fix It” tool, which will remove any leftover files that might cause the same problem.

By following this procedure, several users have confirmed they have been able to launch Office applications without activation errors after following it. Based on this, a corrupt installation of Office that does not check for license keys is likely to be responsible for the problem.
