Access Database Error in Loading DLL – Easy Solutions

How to Fix Access Database ‘Error in Loading DLL’?

There are various solutions to fix this error. However, methods may vary depending on the reason that has resulted in the DLL error. So, identifying the cause behind the error offers great help in resolving error 48.

Note: Solution 1 and Solution 2 only apply to Access users using the .mdf database file.

Solution 1: Try Registering the Dao360 and Msado15 DLL Files

Microsoft recommends registering the Dao360 and Msado15 DLL files with the help of the Regsvr32.exe program to fix the error. To do so, perform the following:

Step 1: Open the Run window by clicking the ‘Windows’ + ‘R’ keys.

Step 2: In the Run window, enter the following command, and then hit the OK button.

Regsvr32.exe "C:\Program Files\Common Files\Microsoft Shared\DAO\Dao360.dll"

Step 3: Next, enter another command and click OK.

Regsvr32.exe "C:\Program Files\Common Files\system\ado\Msado15.dll"

Once the files are successfully registered, check if the issue is resolved. If not, move to the next method.

Solution 2: Update MDAC (Microsoft Data Access Components)

Another Microsoft Official solution to resolve the ‘Error loading in DLL’ issue is to update MDAC. For this, you need to install the latest MDAC version from here.

Solution 3: Program Reinstallation

Some Access users have reported that simply reinstalling the MS Access program helped them fix the error. But, while reinstalling the program, check if the program is sharing the DLL file with any other program. If so, you should not reinstall the Access application as it will disturb other programs.

Moreover, if any doubt prevails in identifying this fact, you should also drop the idea of program reloading. For example, if a user gets an error in loading DLL access, before removing the access program, the user should ensure that the program is not sharing DLL files.

Solution 4: Repair and Clear the Registry

The Windows registry registers every action that takes place in a system if an error occurs. When a DLL error appears, the Windows registry gets modified at the same time. Scanning the Windows registry to fix and clear errors may help in fixing the error. The Windows registry registers every action in a system if an error occurs.
