Error code 0-2.31 during an offline installation of Microsoft 365 Personal typically indicates a problem during setup that can often be resolved by reinstalling using a fresh offline installer image and ensuring the environment is clean.

Use the following steps:

1. Remove the existing Office installation
   • Uninstall Microsoft 365/Office from Settings → Apps → Installed apps (or Control Panel → Programs and Features on older Windows).
   • If standard uninstall fails or leaves remnants, use the automated uninstall tool described in Uninstall Office automatically, then restart the PC.
2. Download a fresh offline installer
   • Go to the Microsoft account dashboard and sign in with the Microsoft account used for the Microsoft 365 Personal subscription.
   • Select Subscriptions.
   • Under Products you've purchased, for a perpetual Office product select Install; for Microsoft 365 Personal select Install Microsoft 365.
   • In the Install Microsoft 365 dialog:
     • Choose the desired language.
     • From Choose a version, select Offline installer.
     • Select Install to download the .img file.
3. Run the offline setup correctly
   • Double‑click the downloaded .img file to mount it as a virtual drive.
   • Open the mounted drive and then the Office folder.
   • Run Setup64.exe (or Setup32.exe if 32‑bit Office is required).
   • Let the installation complete; wait for the You're all set message and then select Close.
4. Activate after installation
   • Ensure the PC is connected to the Internet.
   • Start Word or Excel.
   • Accept the license terms and, if prompted, sign in with the same Microsoft account to activate.

If the error persists even with a fresh offline image, verify that no security or application‑masking tools (such as FSLogix rules hiding Office executables) are blocking setup*.exe or OfficeClickToRun.exe, then retry the installation after removing such rules and restarting.
