Fix Microsoft Office Installation Errors 30015-2025 and 0-1012
Question details
The user needs to install Microsoft Office without resetting or reinstalling Windows.

- Product
- Microsoft Office and Microsoft 365
- Device & OS
- Windows 10 laptop
- Scenario
- Installing Office on a laptop with separate NVMe and SATA drives after removing a previous Office installation.
- Observed behavior
- Installation fails with errors 30015-2025 (1610) and 0-1012 (0). Previous removal, registry cleanup, SFC, and Microsoft troubleshooting tools have not resolved the issue.
Confirm which Microsoft account owns the Office license and check the free space on the Windows system drive, usually C:. Keep the exact error codes available and make sure the laptop has a stable internet connection.
Install Office from the licensed Microsoft account
Use the official account installer and check the system drive even if another drive has more free space.
Open File Explorer > This PC and check the available space on Windows (C:). Standard retail Microsoft 365 installations use the system drive, so free space on a separate SATA drive does not replace space on C:.
Go to office.com/myaccount and sign in with the Microsoft account used to purchase or activate Office. Check that the Office product or subscription is listed.
Select the Install option for your Office product, download the installer, and open the downloaded file. Keep the internet connection stable while setup runs.
If an earlier Office installation is still present, use Microsoft's official Office uninstall troubleshooter, restart Windows, and try the account installer again. If you have already completed this step, move on to the system and hardware checks.

Check Windows and ASUS hardware before retrying
Use these checks when Office still fails after official removal and a fresh installer download.
Work on Office documents with WPS Office
WPS Office is a free, lightweight alternative with a familiar interface for working on documents, spreadsheets, and presentations. It supports common Microsoft Office formats, making it easier to move existing files without waiting for the Microsoft Office installation issue to be resolved.

Frequently Asked Questions
Do I need to reinstall Windows to fix these Office errors?
Not necessarily. First try the installer from office.com/myaccount, check space on C:, run DISM and available hardware diagnostics, and contact Microsoft Support if the errors continue.
Which drive needs free space for a retail Microsoft 365 installation?
Check the Windows system drive, usually C:, in File Explorer > This PC. Free space on a separate drive does not replace the space needed on the system drive.
How do I run ASUS diagnostics on my laptop?
Open MyASUS and look for System Diagnosis under Customer Support. Run the available storage and other relevant tests. The options depend on your laptop model and MyASUS version.
What should I do if SFC reports no integrity violations?
Record the result, run DISM /Online /Cleanup-Image /RestoreHealth from an administrator command window, and check available hardware diagnostics. If Office still fails, share the results and error codes with Microsoft Support.
