Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi @Mo Imran,
Welcome to Microsoft Q&A forum.
Thank you for reaching out. I understand you're running into an issue while trying to complete the Office setup process, and I’ll be glad to help you troubleshoot what’s causing the installation to stop.
Here are a few suggestions you can try to troubleshoot:
1/ Perform a clean uninstall and reinstall
A restart and clean removal often resolves setup failures.
- Restart your device and try running the Office installer again.
- If the installation still doesn’t complete, use Microsoft’s official Support and Recovery Assistant to fully uninstall Microsoft 365/Office, then reinstall it.
- You can find the uninstall tool and installation guidance in Microsoft Support’s “Troubleshoot installing Office” resources.
If you have the Get Help app, Microsoft also provides a dedicated Microsoft 365 setup troubleshooter for installation, activation, or sign‑in issues: Microsoft 365 troubleshooters - Microsoft Support.
2/ Collect the installation logs (takes 2–3 minutes)
Office setup logs are generated automatically and can help identify the exact point of failure.
Check the following folders:
- %temp% (user temp folder)
- %windir%\Temp (system temp folder)
Look for files named:
-
Microsoft Office Setup (####).txt -
Microsoft Office Setup (####)_Task(0001).txt,Task(0002).txt, etc.
Open the most recent files (with the highest ####).

In the MSI log, search for:
- “Value 3” – common error marker
- “Rolling back package” – indicates where the failure started
Microsoft provides guidance on how to interpret these logs in: Troubleshooting Office installation failures.
3/ Confirm you're using the correct installation method
For Microsoft 365 Apps, make sure you're installing from your licensed portal:
- Sign in to your Microsoft 365 account.
- Select Install Microsoft 365 apps.
- Download and run OfficeSetup.exe, then approve the UAC prompt.
This ensures the correct build and licensing are applied: Download and install apps.
If the issue continues:
Your IT support team may need to review the logs or installation environment. If needed, they can also open a support ticket through the Microsoft 365 Admin Center for deeper analysis.
I hope this information helps. Please try the steps and let me know whether they resolve the issue. If the problem persists, we can work together to find a solution.
