How to Fix Microsoft Office Error Code 30015-28?

When users encounter the Microsoft Office Error Code 30015-28, the installation or update process typically fails, displaying this error, indicating a problem with the installation files or a conflict with existing software on the system. The most common cause of this issue is a corrupted Office installation or remnants of a previous installation interfering with the new setup.

Additionally, issues such as insufficient permissions, antivirus software blocking the process, or network connectivity problems can contribute to this error.

In this article, we will discuss different fixes to solve this issue and update Microsoft Office.

1. Run SFC and DISM

The problem can occur due to corrupted system files. Running SFC (System File Checker) and DISM (Deployment Image Servicing and Management) utilities will scan for corrupted files, perform repairs, and restore system integrity.

  1. Open the Search menu, type cmd, and run the Command Prompt as an Administrator.
  2. Enter the following commands:
    sfc /scannow
    Dism /Online /Cleanup-Image /RestoreHealth

  3. Restart your PC once the processes are completed.

2. Disable Antivirus

A third-party antivirus program might conflict with the normal update process of Microsoft Office. Disabling such programs can often clear this error. Disable your antivirus by following these steps.

3. Use Online Repair Tool

Using the online repair tool will scan the MS Office files and fix any issues, which can help in solving your problem.

Note: Ensure you have a stable Internet connection before starting the repair, as it requires downloading files from Microsoft servers.

  1. Press Windows + R, type ‘appwiz.cpl’ and press Enter.
  2. Look for Microsoft Office, right-click on it and hit Change.
  3. Select Online Repair and press Repair.
  4. Wait for this process to finish.

4. Clean Boot

Third-party services can interfere with programs and cause issues. To determine if they are the cause, try performing a clean boot of Windows; this stops all non-Microsoft services from running at startup, which might resolve the problem.

  1. Press Windows + R, type ‘msconfig‘, and press Enter.
  2. Navigate to the Services tab, tick the Hide all Microsoft Services checkbox, click Disable all, and click OK.
  3. Press Windows + SHIFT + ESC to open the Task Manager.
  4. Switch to the Startup tab and disable all third-party programs.

5. Reinstall Office

If none of the solutions work, you can reinstall MS Office. The error might be due to corrupted files or a glitch, and reinstalling will delete the existing installation and install a fresh and latest version of MS Office.

You can download Office from Microsoft’s Official Website.
