Fixing Microsoft Office 2021 Error Code 0‑2054

Office 2021 may show error 0‑2054 during installation, activation, or updates when setup encounters issues—typically due to incomplete installs, corrupted installer files, leftover Office components, or permission conflicts. This prevents Office from installing or updating properly.

To resolve it, follow these steps:

1. Restart your PC to clear any temporary locks or processes.


2. Run the installer or updater as administrator: Right-click and choose “Run as administrator” to bypass permission issues.


3. Fully remove existing Office installations: Use the Microsoft Support and Recovery Assistant or the Control Panel → Programs and Features to uninstall all Office versions.


4. Delete leftover Office files from these folders (if present):
   

   %ProgramFiles%Microsoft Office  
   
   %ProgramFiles(x86)%Microsoft Office  
   
   %localappdata%MicrosoftOffice
   
   

   
   


5. Temporarily disable antivirus or firewall software that could interfere with the process.


6. Repair system files: Open Command Prompt as administrator and run:
   

   sfc /scannow
   
   

   
   


7. Reboot your computer, then run the Office setup or update again as administrator.
