Error 30068-39
Microsoft Microsoft Office
Severity: ModerateWhat Does This Error Mean?
Error 30068-39 appears when a Microsoft Office installation or update is interrupted or fails to complete. This error often means that files were downloaded but could not be written to your computer correctly. A repair or clean reinstall of Office fixes this in most cases.
Affected Models
- Microsoft Office 2019
- Microsoft Office 2021
- Microsoft 365
Common Causes
- A previous Office installation or update was interrupted mid-process, leaving files in an incomplete state
- Another program (like antivirus software) blocked the Office installer from writing files
- Insufficient disk space on the drive where Office is being installed
- Corrupted Office installer files that were downloaded with errors
- A conflict with a previous version of Office that was not fully removed before installing
How to Fix It
-
Run the Microsoft Support and Recovery Assistant (SaRA). Download it free from support.microsoft.com. It is Microsoft's official tool for fixing Office installation problems.
SaRA automates many of the manual steps and is the fastest way to resolve install errors.
-
Check your available disk space. Office needs at least 4 GB free. Open File Explorer and right-click your C: drive to see free space.
If you are low on space, delete temporary files or move documents to an external drive before retrying.
-
Temporarily disable your antivirus software before retrying the installation or update.
Remember to turn your antivirus back on immediately after Office finishes installing.
-
Go to Control Panel > Programs > Programs and Features, find Microsoft Office, click Change, and run Online Repair.
Online Repair downloads fresh copies of all Office files and replaces any that are damaged.
-
If repair does not work, fully uninstall Office using the Microsoft Support and Recovery Assistant's uninstall option, then download a fresh installer from office.com and reinstall.
Use the SaRA uninstall option rather than the normal uninstall — it removes hidden leftover files that cause repeated failures.
When to Call a Professional
Error 30068-39 is almost always fixable without professional help. If Office still fails after trying a clean reinstall and using the Microsoft Support and Recovery Assistant, contact Microsoft Support directly. They can run remote diagnostics and push a clean installation to your machine.
Frequently Asked Questions
What is the Microsoft Support and Recovery Assistant?
The Microsoft Support and Recovery Assistant (SaRA) is a free tool from Microsoft. It automatically diagnoses and fixes common problems with Office, Outlook, and other Microsoft products. You can download it from support.microsoft.com — just search for 'SaRA tool'.
Do I need to buy Office again if I have to reinstall?
No. Your Office license is tied to your Microsoft account, not the installation. As long as you sign in with the same Microsoft account during reinstallation, your license is recognized automatically. You will not be charged again.
Error 30068-39 appeared during an automatic update — is my current Office broken?
Your existing Office installation is likely still working. The error means the update could not be applied, but the previous version remains intact. You can continue using Office while you fix the update problem.
