Question details

Users encounter an OLE server or ActiveX control error in Microsoft Access after upgrading the operating system.

Fixing Access OLE Server and ActiveX Errors on Windows 11

Product: Microsoft Access
Device & OS: Windows 11
Scenario: Clicking a command button in an Access database that previously worked perfectly on Windows 10.
Observed behavior: The application throws an error referencing an OLE server, ActiveX controls, macros, user-defined functions, or event procedures, preventing the command button from functioning.

Before you start

Ensure you have administrative privileges on your Windows 11 computer, as you may need to modify Microsoft Access Trust Center and security configurations.

Solution 1Recommended

Configure ActiveX and Macro Settings in Trust Center

Adjusting the Trust Center settings can resolve security blocks on ActiveX controls and macros triggered by the stricter defaults in Windows 11.

Windows 11 often resets or applies stricter security protocols to Office applications. If the VBA references match between your old and new PCs but the error persists, updating the Trust Center settings is the most effective fix.

Open Trust Center

Launch Microsoft Access, click on 'File' in the top-left corner, select 'Options', and then navigate to the 'Trust Center' tab.

Access Trust Center Settings

Click the 'Trust Center Settings...' button to open the detailed security configuration window.

Adjust ActiveX Settings

Select 'ActiveX Settings' from the left pane. Choose 'Prompt me before enabling all controls with minimal restrictions' and click 'OK'.

Enable Macros and Trusted Locations

Navigate to 'Macro Settings' and select 'Enable all macros' (if the database is from a trusted source). Then, go to 'Trusted Locations', add the folder containing your database, and restart Access.

Configure ActiveX and Macro Settings in Trust Center

Security Prompt: Adding your database folder to Trusted Locations often bypasses the need to lower your global macro security settings, keeping your system safer.

Solution 2

Verify and Repair VBA References

Ensure that all required object libraries are properly linked and not marked as missing in the VBA editor.

Frequently Asked Questions

Why does this ActiveX error only happen on Windows 11?

Windows 11 introduces updated security protocols and stricter default settings for Office applications. This can block older ActiveX controls or macros that executed without issue on Windows 10 until you explicitly trust them.

Will reinstalling Microsoft Office fix the OLE Server error?

Not necessarily. A reinstall might reset some basic configurations, but security-blocked controls usually require manual adjustments to the Access Trust Center settings and VBA references.

What if the ActiveX control is not listed in the VBA References?

ActiveX is a general technology category and will not appear directly as 'ActiveX' in the references list. You should look for specific .ocx or .dll files related to the control you are using, or resolve the issue via Trust Center.

How do I add a Trusted Location in Access?

Go to File > Options > Trust Center > Trust Center Settings > Trusted Locations. Click 'Add new location', browse to the folder containing your database, check 'Subfolders of this location are also trusted', and click OK.
