How to Fix an Office Installation Stuck at 90%
A Microsoft Office installation that appears to be stuck at 90% is a common and frustrating problem. This issue often occurs because of a conflict with another process, a network problem, or corrupted system files. The installation can appear to be frozen, but in many cases, it is just waiting for a conflicting task to finish or a file to be accessed.

This guide provides a series of effective solutions to get your Office installation unstuck and completed successfully.

Understanding the “Stuck at 90%” Issue
The “90%” mark is a common point of failure because it’s where the installer often transitions from downloading to configuring the software. The most likely causes for the installation to freeze at this stage are:

Conflicting Processes: A running Windows Update, another installation, or a background process is locking files that Office needs to access.

Internet Connection Issues: A slow or unstable internet connection can interrupt the download of the final installation files.

Antivirus or Firewall Interference: Security software can sometimes block the Office installer from accessing or writing to critical system files.

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

Solution 1: Use the Offline Installer
This is often the most reliable solution if the problem is network-related. It bypasses any potential internet connection issues by allowing you to download all the installation files in one go.

Go to your Microsoft account’s Services & subscriptions page.

Find your Office product and click “Install.”

In the download window, select “Other options” or a similar link.

Choose the “Offline installer” option and download the file to your computer.

Disconnect your internet connection and run the offline installer. This method bypasses internet-related issues during the final installation phase.

Solution 2: Check for Conflicting Processes
A running Windows Update or another busy Windows Installer can be the culprit.

Press Ctrl + Shift + Esc to open Task Manager.

Go to the Processes tab and look for any of the following processes:

wusa.exe (Windows Update Standalone Installer)

setup.exe (Another installer)

msiexec.exe (Windows Installer)

If you see these processes running, click on them and select “End task.”

The Office installation should now resume and complete.

Solution 3: Temporarily Disable Antivirus and Firewall
Security software can sometimes incorrectly flag the Office installation as a threat and block its progress.

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.

Solution 4: Clean Up Temporary Files
Corrupted temporary files can also cause installation failures.

Press the Windows key + R, type %temp%, and press Enter to open your temporary files folder.

Select all files (Ctrl + A) and delete them. You may need to skip a few files that are currently in use.

Maak die opdragprompt as 'n administrateur oop.

Type sfc /scannow and press Enter to scan for and repair corrupted system files.

After the scan, restart your computer and try the installation again.

Q: I still get the error even after a clean boot. What’s wrong?
A: If all else fails, a deeper issue may exist. The next step is to use the Microsoft Support and Recovery Assistant tool to perform a complete and clean removal of any Office remnants. You can then try installing again.

Q: Is it safe to disable my antivirus?
A: Yes, it is safe to temporarily disable your antivirus for the duration of the installation, as long as you re-enable it immediately afterward.

Q: I don’t have a fast internet connection. Will the offline installer help?
A: Yes. The offline installer allows you to download a large file once and then install it without any further internet dependencies, making it ideal for slow or unreliable connections.
