Observed behavior: Office displays error 0x80004005 stating the product cannot be used in shared scenarios, applications appear unlicensed, or application shortcuts are missing from the Start menu.

Solution 1Recommended

Enable Shared Computer Activation via the Windows Registry

Manually set the required registry key to force shared computer licensing and verify the activation status inside the Office application.

If the Office Deployment Tool or Support and Recovery Assistant fail to apply the setting, manually updating the Windows Registry is the most direct way to enforce shared computer activation and clear error 0x80004005.

Open the Registry Editor

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

Navigate to the Office Configuration Key

Go to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration.

Set the Licensing Value

Look for a string value named 'SharedComputerLicensing'. If it does not exist, right-click, select New > String Value, and name it 'SharedComputerLicensing'. Double-click it and set its value data to '1'.

Verify Activation in Office

Open Word or Excel and sign in with a valid Microsoft 365 Business Premium account. Click on File > Account > About. The screen should now explicitly display 'Shared Computer Activation'.

Enable Shared Computer Activation via the Windows Registry

Locating Missing Application Shortcuts: If Office applications do not appear in the Start menu after installation, open File Explorer and navigate to C:\Program Files\Microsoft Office\root\Office16 (or Program Files (x86) for 32-bit). You can directly launch or create desktop shortcuts for WINWORD.EXE, EXCEL.EXE, and POWERPNT.EXE from here.

Solution 2

Deploy Office using the Office Deployment Tool (ODT)

Use a configuration XML file to automatically enable shared computer activation during the initial installation of Microsoft 365 Apps.

Frequently Asked Questions

Why am I getting error 0x80004005 when opening Microsoft 365 Apps?

Error 0x80004005 typically occurs in shared computer environments (like Remote Desktop Services) when Microsoft 365 Apps are installed without the Shared Computer Activation feature enabled, or if the logged-in user lacks a qualifying license.

Does Microsoft 365 Business Standard support shared computer activation?

No. Shared computer activation is supported by Microsoft 365 Business Premium and Microsoft 365 Apps for enterprise, but it is not included in the Microsoft 365 Business Standard subscription plan.

Where can I find my Office apps if they are missing from the Windows Start menu?

You can launch the applications directly from their installation folder. Navigate to C:\Program Files\Microsoft Office\root\Office16 for 64-bit Office, or C:\Program Files (x86)\Microsoft Office\root\Office16 for 32-bit Office, and look for executable files like WINWORD.EXE or EXCEL.EXE.
