How to Uninstall Access Database Engine 2010 Not Listed in Windows 11
Question details
The user needs to remove a legacy Microsoft Access Database Engine 2010 installation that is hidden from the Windows 11 Apps list and is preventing the installation of 64-bit Microsoft 365.
- Product
- Microsoft Access Database Engine 2010 / Microsoft 365
- Device & OS
- Windows 11
- Scenario
- Attempting to install 64-bit Microsoft 365 but being blocked by a persistent, hidden 32-bit Access Database Engine 2010 component.
- Observed behavior
- The 32-bit database engine remains installed after removing Microsoft 365, does not appear in the Windows 11 'Installed apps' menu, and throws an architecture conflict error when a 64-bit Office installation is attempted.
Ensure you are logged into Windows 11 with an Administrator account, as you will need elevated Command Prompt privileges and access to the Windows Registry to identify and remove the hidden product GUID.
Force Uninstall Using Command Prompt and Product GUID
Use this method to manually locate the hidden installation's identifier in the registry and forcefully remove it using the Windows Installer command-line tool.
Since the software is not listed in your standard Windows 11 Apps menu, you must locate its unique product GUID. Once found, the 'msiexec' command will bypass the missing GUI uninstaller and forcefully remove the component.
Press the Windows key, type 'regedit', and press Enter to open the Registry Editor. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and look through the folders to find the one associated with Access Database Engine 2010. Copy the Product GUID (e.g., {90140000-2005-0000-0000-0000000FF1CE}).
Click the Windows 11 Start button, type 'cmd' into the search bar, right-click on 'Command Prompt', and select 'Run as administrator'.
In the Command Prompt window, type 'msiexec /qn /x {product-GUID}' (replacing {product-GUID} with the exact code you copied from the registry) and press Enter. The silent uninstallation will run in the background.

Frequently Asked Questions
Why does the 32-bit Access Database Engine block a 64-bit Microsoft 365 installation?
Microsoft Office restricts mixing 32-bit and 64-bit architecture components on the same machine. Because the Access Database Engine acts as an Office component, a leftover 32-bit installation triggers an architecture conflict, forcing the 64-bit installer to halt until the legacy component is removed.
Where else can I find the product GUID if it is not in the Windows Registry?
If you cannot find the GUID in the registry, you can search the Microsoft Office installation log files located in your %temp% folder. Alternatively, you can open Windows PowerShell as an administrator and run 'Get-WmiObject -Class Win32_Product' to list installed software and their identifying codes.
Can I simply delete the Access Database Engine files from my Program Files folder?
No. Manually deleting the files from your hard drive will not remove the associated registry keys or unregister the product from Windows Installer. The installer will still detect the software as 'installed', and your new Office installation will continue to be blocked.
