Question details

Users are unable to use the Mail Merge Wizard in Microsoft Access because the system incorrectly states that Microsoft Word is required, even though it is already installed.

How to Fix the Microsoft Word Required Error in Access Mail Merge

Product: Microsoft Access
Device & OS: not provided
Scenario: Running the Mail Merge Wizard to export or merge data from Microsoft Access to Microsoft Word.
Observed behavior: The system blocks the Mail Merge process by displaying a 'Microsoft Word is required to run the Mail Merge Wizard' error, and occasionally shows a false warning about macros in untrusted locations.

Before you start

Verify that Microsoft Word and Microsoft Access are installed on the same device and are operating under the same Microsoft 365 license or Office suite edition.

Solution 1Recommended

Revert to an Earlier Office Build

Since this error is closely tied to specific Microsoft 365 updates (such as Version 2305), reverting to an earlier, stable build like Version 2304 is the most effective workaround.

Microsoft has acknowledged that certain recent updates contain a bug that breaks the communication between Access and Word during a Mail Merge. Rolling back your Office installation temporarily bypasses this bug.

Disable Automatic Updates

Open Microsoft Access, go to File > Account, click on 'Update Options', and select 'Disable Updates' so your rollback isn't immediately overwritten.

Open Command Prompt as Administrator

Click the Start menu, type 'cmd', right-click 'Command Prompt', and select 'Run as administrator'.

Run the Revert Command

Type the command to revert to your previously known working version (e.g., Version 2304) using the Office Click-to-Run executable, and press Enter.

Reinstallation Alternative: If you are unsure how to use the Command Prompt, completely uninstalling Office and reinstalling a slightly older offline package will achieve the same result.

Solution 2

Update to the Latest Office Release

Because Microsoft is actively aware of this Mail Merge issue, checking for the most recent updates may download an official hotfix that repairs the bug.

Solution 3

Run an Online Repair of Microsoft Office

If the issue is caused by a corrupted installation rather than a version bug, repairing the Microsoft 365 suite can restore the necessary registry keys that allow Access to detect Word.

Frequently Asked Questions

Why does Access say Microsoft Word is not installed when it is?

This is a known bug in specific builds of Microsoft 365 (like Version 2305). The update disrupts the background communication between Access and Word, causing Access to fail to recognize the Word installation during the Mail Merge Wizard.

Is the untrusted location macro warning related to this error?

Yes. Users experiencing the Mail Merge bug often report a secondary false warning claiming that macros are in an untrusted location, even when the file path has been correctly added to the Trust Center. Fixing the version issue typically resolves both errors.

How do I check which version of Office I am running?

Open any Office application like Access or Word, click on File, and select Account. Under the 'About Access' or 'About Word' section, you will see your current Version and Build numbers.

Will running an Online Repair delete my Access databases?

No, repairing Microsoft Office only checks and replaces the application's program files and registry entries. Your personal documents, spreadsheets, and Access database files will remain untouched.
