How to Fix Office Professional Plus 2016 Error 30147-45 During Repair
Question details
The user is unable to open Microsoft Office Professional Plus 2016 and encounters error 30147-45 when attempting an online repair after an offline repair also failed.
- Product
- Microsoft Office Professional Plus 2016
- Device & OS
- not provided
- Scenario
- Attempting to fix a corrupted Office 2016 installation that will not launch using the built-in Windows repair tools.
- Observed behavior
- The Office applications fail to open, the offline repair process fails, and the online repair process returns the specific error code 30147-45.
Ensure you have your Microsoft Office product key or your Microsoft account login credentials readily available, as you will need them to activate the software after the reinstallation process.
Completely Uninstall and Reinstall Office 2016
Use the official Microsoft Support and Recovery Assistant to clean up corrupted files and registry keys before performing a fresh installation.
When both offline and online repairs fail with error 30147-45, the underlying installation files or registry entries are severely corrupted. A standard Windows uninstallation will not clear these hidden corruptions, requiring the use of Microsoft's dedicated uninstall support tool.
Visit the official Microsoft Support website and download the Microsoft Support and Recovery Assistant (SetupProd_OffScrub.exe).
Double-click the downloaded executable file to install and launch the Microsoft Support and Recovery Assistant.
In the application window, select 'Office' and then choose 'Office Professional Plus 2016' from the list of installed products. Click 'Next'.
Follow the on-screen prompts to confirm the complete removal of the Office suite. Once the tool finishes processing, restart your computer.
Log in to your Microsoft account portal (account.microsoft.com), navigate to your 'Services & subscriptions' section, locate Office Professional Plus 2016, and click 'Install' to perform a fresh installation.
Avoid Complex Installation Errors with WPS Office
If you are tired of dealing with persistent installation errors, failed online repairs, and corrupted software like error 30147-45, try WPS Office. It provides a lightweight, hassle-free alternative that installs in seconds and easily handles all your document needs.
Frequently Asked Questions
What causes error code 30147-45 during an Office online repair?
This error typically occurs due to severely corrupted core installation files, conflicting registry entries from previous Office versions, or a disrupted background service that prevents the online repair tool from communicating with Microsoft servers.
Will using the uninstall tool delete my saved Word and Excel documents?
No. The Microsoft Support and Recovery Assistant only removes the Microsoft Office application files, settings, and registry entries. Your personal documents, spreadsheets, and presentations saved locally on your drive will remain untouched.
Can I fix error 30147-45 without reinstalling the entire Office suite?
Generally, no. Since both the offline and online repair options have already failed, it indicates the corruption is too deep for a simple patch. A complete uninstallation and fresh reinstallation is the most reliable way to restore functionality.
