Question details

- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario

Perform a Clean Uninstall and Restart
Use the official support tool to remove corrupted files or conflicting residual components from previous Office versions.

Navigate to the official Microsoft Support website and download the Microsoft Support and Recovery Assistant (SaRA) tool.
Open the downloaded SaRA application, select 'Office', and then choose the option 'I have Office installed, but I'm having trouble uninstalling it'.
Follow the on-screen prompts to completely wipe all Microsoft 365 and Office components. Once finished, click 'Restart' to reboot your computer and apply the changes before attempting a fresh installation.
Install Microsoft 365 Offline
Bypass potential network and firewall issues by using the Microsoft 365 offline installer.
Create a New Windows User Profile
Test the installation from a fresh Windows profile to rule out corrupted user permissions or settings.

Frequently Asked Questions
Can I still use the Office apps if error 0-2031 (17002) appears?
Yes, in many cases the applications like Word and Excel will still open. However, the installation is considered corrupted, meaning you may experience instability, missing features, or failure to receive future security updates until it is properly reinstalled.
What causes Microsoft 365 installation error 0-2031 (17002)?
This error is typically triggered by residual files from a previous Office installation, overly strict third-party security software blocking the final setup steps, or brief network connection interruptions.
Why should I use the Microsoft 365 offline installer?
The standard installer requires a constant internet connection to download components on the fly. The offline installer downloads all necessary files at once, which bypasses potential firewall, proxy, or unstable network issues during setup.
Will using the Support and Recovery Assistant delete my Word documents?
No. The Microsoft Support and Recovery Assistant only removes the software application files, system registry keys, and shortcuts related to Microsoft 365. Your personal documents, spreadsheets, and presentations will remain safe on your hard drive.
