Question details

The user needs to resolve a DLL loading error that prevents a Microsoft Access application from running properly on a single computer within a local area network.

Product: Microsoft Access
Device & OS: not provided
Scenario: Running a networked Microsoft Access application on a specific computer within a LAN environment.
Observed behavior: A DLL error is reported on only one PC. Reinstalling Microsoft Office does not fix the issue, indicating potential VBA/DAO library corruption or a broken registry.

Before you start

Ensure you have administrative privileges on the affected computer and note down the exact name of the missing or failing DLL file mentioned in the error prompt or VBA reference list.

Solution 1Recommended

Copy the Required DLL from a Working Computer

Replace the corrupted or missing DLL file by copying a healthy version from another PC on the same network that runs the Access application successfully.

Identify the missing DLL

Open Microsoft Access on the failing computer, press Alt + F11 to open the VBA Editor, navigate to Tools > References, and note the file path for any entry marked as 'MISSING'.

Locate the file on a healthy PC

On a working computer running the exact same Windows and Office version, navigate to the folder path you noted (often in C:\Windows\System32 or C:\Program Files\Common Files).

Transfer the file

Copy the healthy DLL file to a USB drive or a shared network folder.

Replace the corrupted file

Paste the copied DLL file into the exact same directory on the failing computer, replacing the existing corrupted file if prompted.

Register the new DLL

Press Win + R, type 'regsvr32 filename.dll' (replace filename with the actual name), and press Enter to register the file in Windows.

Solution 2

Repair Corrupted Registry Keys

Address potential registry corruption that prevents the DLL from loading even after the Office suite has been reinstalled.

Frequently Asked Questions

Why did reinstalling Microsoft Office not fix the DLL error?

Reinstalling Office often relies on existing registry entries and shared system files. If the registry path is corrupted or a shared Windows DLL (like a common DAO/VBA library) is damaged, a standard reinstallation will not overwrite or fix these specific shared components.

How do I find exactly which DLL is causing the Access error?

Open your Microsoft Access database and press Alt + F11 to open the VBA editor. From the top menu, go to Tools > References. Look for any checked items in the list marked with the word 'MISSING:'. The file path and name listed next to it is the exact DLL causing the issue.

Can I use WPS Office to open Microsoft Access (.accdb) files?

WPS Office does not include a direct relational database application like Microsoft Access. However, if you only need the data, you can export your Access tables to Excel formats (.xlsx or .csv) and open them flawlessly in WPS Spreadsheet.
