Microsoft Office Error Code 0‑2054 typically occurs during the installation or update of Office 2021 or Microsoft 365. This issue is usually caused by residual files from previous Office installations, registry conflicts, or corrupted setup components that interrupt the process.
To resolve this, start by removing older versions of Office through the Control Panel or the Settings app. After uninstallation, delete any remaining Office-related folders from C:Program Files and C:Program Files (x86), and clear temporary files from the %temp% directory.
Disable any antivirus or firewall temporarily to avoid interference during installation. Then, open Command Prompt as administrator and run sfc /scannow to scan and repair any corrupted system files. You can also use the Microsoft Support and Recovery Assistant tool to detect and fix deeper setup issues.
Once the system is ready, download a fresh Office installer from your copyright and proceed with a clean installation.
