Office may display error 0‑2054 during installation or updates when the setup tool encounters configuration issues—often due to incomplete installs, corrupted installer files, leftover Office components, or permission conflicts. This error interrupts setup and prevents Office from installing. To resolve it, restart your PC to clear temporary glitches, then run the installer or update as an administrator to bypass permission issues. If the error persists, fully uninstall any existing Office versions using the Microsoft Support and Recovery Assistant, and delete residual folders in
%ProgramFiles%Microsoft Office, %ProgramFiles(x86)%Microsoft Office, and %localappdata%MicrosoftOffice. Temporarily disable antivirus or firewall software that might interfere during installation, then open an elevated Command Prompt and run sfc /scannow to repair corrupted system files. After rebooting, relaunch the Office setup or updater. These steps typically resolve error 0‑2054 and restore Office installation.
