Use Microsoft Support and Recovery Assistant to Clean Remnants
This is the most reliable method to clear residual files from older Office versions that are blocking your new installation.
Installation errors like 30015-2016(5) usually occur because files or background services from a previous Office installation were not completely removed. The official cleanup tool automates the process of finding and securely deleting these remnants.
Reboot your PC first to see if the stalled installation resumes on its own. If it continues to fail, proceed to the next step.
Download the Microsoft Support and Recovery Assistant (SaRA) Office uninstall tool from the official Microsoft website and run the downloaded executable.
Follow the on-screen prompts in the tool to completely identify and remove all remnants of previous Office installations from your system.
Restart your computer once the cleanup finishes. Log into your Microsoft account, navigate to the Services and subscriptions page, and start the Office installation again.
Avoid Installation Errors with WPS Office
If Microsoft Office continues to fail during setup with errors like 30015-2016(5), consider switching to WPS Office. It provides a lightweight, instant installation process without the complex registry or background service dependencies that cause Microsoft Office to stall.

Frequently Asked Questions
Why do I get error 30015-2016(5) when installing Microsoft Office?
This error is typically triggered when remnants of a previously uninstalled version of Microsoft Office conflict with the new setup files. It prevents the new installation from writing necessary registry keys or files.
Can I fix the 30015 installation error by deleting registry keys?
It is highly discouraged to manually delete registry keys to fix Office errors. Incorrectly modifying the registry can cause system instability or permanent damage. Always use the official Microsoft Support and Recovery Assistant.
What should I do if the installation remains stalled after using the cleanup tool?
If the installation still stalls, verify that your internet connection is active, as background downloads are required. Ensure you give the installer additional time, and double-check that third-party antivirus software isn't silently blocking the process.
