How to Fix Office “Something Went Wrong” Error During Setup
The “Something went wrong” error is a generic but frustrating issue that can stop a Microsoft Office installation in its tracks. This error message is typically accompanied by a specific error code, such as 30015-11, 30015-1011, or 30088-26. The common causes are conflicts with previous Office installations, corrupted system files, or interference from third-party applications.

This guide will walk you through a series of effective solutions to resolve this error and successfully install your Office suite.

Understanding the “Something Went Wrong” Error
This error is a broad signal that the Office installer has encountered an unexpected problem. The primary causes are:

Previous Office Installations: Remnants of an older or failed Office installation can conflict with the new setup.

Corrupted System Files: Damaged Windows or Office files can prevent the installer from completing its tasks.

Firewall or Antivirus Interference: Security software can block the installation process, preventing the installer from writing files to the disk.

Network or Proxy Issues: A bad internet connection or a misconfigured proxy server can cause the installer to fail.

Solution 1: Use the Microsoft Support and Recovery Assistant
Microsoft’s Support and Recovery Assistant (SaRA) is a powerful tool designed to diagnose and fix a wide range of Office installation problems, including the “Something went wrong” error.

Download the Microsoft Support and Recovery Assistant from the official Microsoft website.

Run the tool and agree to the license terms.

Select the “Office” product and choose the option that best describes your problem, such as “I need help installing Office.”

The tool will automatically diagnose the issue, perform a full and clean removal of any old Office remnants, and guide you through the reinstallation process.

Solution 2: Manually Uninstall Old Office Versions
If the SaRA tool doesn’t work, you can manually uninstall older versions of Office to ensure a clean slate.

Press the Windows key + R, type control, and press Enter to open the Control Panel.

Go to Programs > Programs and Features.

Find any Microsoft Office products in the list and uninstall them.

For a more thorough cleanup, follow the steps in this Microsoft support article to manually remove all Office remnants using the registry.

Solution 3: Check for Corrupted System Files
Corrupted system files can cause installation failures. The System File Checker (SFC) can find and repair these files.

Ανοίξτε τη Γραμμή εντολών ως διαχειριστής.

Type the following command and press Enter:
sfc /scannow

Wait for the scan to complete.

Next, run the DISM tool to repair the system image:
DISM /Online /Cleanup-Image /RestoreHealth

After the scans are finished, restart your computer and try the Office installation again.

Solution 4: Temporarily Disable Antivirus and Firewall
Security software can sometimes block the Office installation process.

Temporarily disable your third-party antivirus software and your Windows Defender Firewall.

Try running the Office installer again.

If the installation is successful, remember to re-enable your security software immediately.

Συχνές ερωτήσεις
Q: I have a specific error code like 30015-11. What does it mean?
A: The specific error code provides more detail, but the troubleshooting steps are generally the same. Most of these codes point to a file-in-use or a conflict with a previous installation. The SaRA tool is the best way to address these.

Q: Will I lose my documents if I uninstall Office?
A: No. Uninstalling Office only removes the applications themselves, not your personal documents. Your Word, Excel, and other files will remain safe.

Q: Can I use the offline installer to avoid this error?
A: Yes. The offline installer can help if the problem is network-related. You can download the full installation package once and run the setup without needing a continuous internet connection.
