How to Fix Microsoft Office Error Code 0‑2054 (Office 2021/365)

Blog Article

Microsoft Office Error Code 0‑2054 typically appears during installation or upgrade of Office 2021 or Office 365 when the setup process is blocked by residual registry entries, security software, or corrupted components from a previous installation. Users often encounter this issue when switching between different Office versions or after failed repair attempts.

To begin fixing this error, first disable any antivirus software and firewall temporarily, as these programs often interfere with Office setup files. On Windows, navigate to Control Panel → System and Security → Windows Defender Firewall, and turn it off for both private and public networks. Then, turn off your antivirus protection from the system tray or software dashboard.

Next, open the Registry Editor and search for leftover keys related to earlier Office versions. These remnants can block new installations. Carefully remove outdated entries after backing up the registry. This step is critical to ensure that previous version data does not conflict with Office 2021.

You should also open Command Prompt as an administrator and run the command sfc /scannow to repair any corrupted system files. Once the scan is complete, restart your system.

After cleanup, reinstall Office by signing into your copyright and downloading a fresh copy. Make sure you have a stable internet connection and that no background processes are interfering with the setup.
