How to Fix Office Activation Error 0x80004005 in Shared Computer Scenarios

Product: Microsoft Office 365
Device & OS: Windows
Scenario: Attempting to activate and use Microsoft 365 Apps for enterprise on a workstation shared by multiple users.
Observed behavior: Microsoft Office fails to authenticate and activate, displaying error 0x80004005 and blocking access to standard Office applications.

Before you start

Ensure you have administrative privileges on the affected Windows device and access to the Microsoft 365 admin center to verify user licenses.

Solution 1Recommended

Verify Enterprise License and Enable Shared Computer Activation

Check that the user has a valid Microsoft 365 Apps for enterprise license and that the Windows registry is correctly configured to allow shared activation.

Shared Computer Activation requires specific enterprise licenses (like Office 365 E3 or E5). If the correct license is assigned but the error persists, the local registry setting enabling this feature might be missing or set incorrectly.

Verify license in Admin Center

Log in to the Microsoft 365 admin center, navigate to Users > Active users, select the affected user, and ensure they have a license that includes 'Microsoft 365 Apps for enterprise'.

Open Registry Editor

Press the Windows key + R, type 'regedit' into the Run dialog, and press Enter to open the Registry Editor as an administrator.

Navigate to the Office Configuration key

Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration.

Enable SharedComputerLicensing

Look for the string value named 'SharedComputerLicensing'. If it exists, ensure its value is set to 1. If it does not exist, right-click, create a new String Value, name it 'SharedComputerLicensing', and set the value data to 1.

Verify Enterprise License and Enable Shared Computer Activation

Restart Required: After modifying the registry, restart the computer to ensure the new licensing configuration takes effect before opening Office apps.

Solution 2

Clear Cached Microsoft Credentials

Corrupted or outdated cached login credentials can prevent Office from authenticating successfully. Removing them forces a fresh login prompt.
