5 Fixes To Resolve Access Library Not Registered Error

In Access library not registered error mainly occurs when during the installation or uninstallation of any software, libraries get overwrite or de-register. After this, you will notice that even simple functions like Trim () or Date () stops working.

If you are dealing with the same problem then this blog is really going to help you a lot. As in this, you will get to know the best fixes to resolve library not registered error in Access 2019/2016/2013/2010/2007.

Besides this we will also discuss the types of libraries in Access and about the problems that arise due to Access library not registered error.

What Is Access Database Library?

Before diving into the fixes let’s take a quick recap of what Access database library is. When the Access database is programmed using VBA code in order to manage other applications objects which are external to the Access database you need to allow permission to use each application’s respective library files. Then only the VBA will work between the Access database and other external applications. These libraries not only give a security layer and but also controls the complete accessing of all the objects.

Here is some more interesting reason to use Access database libraries:

  • Increases the performance by running or loading your application at a faster pace.
  • Enhances the Access database memory usage
  • Offers the best security for keeping your intellectual property completely safe.
  • Easy sharing of database projects across multiple developers.
  • Gives stability to the Access database front-end.
  • It’s been so easy to maintain as the code size of the Access database front end is less complex and small. Thus there will be fewer chances Access database corruption.

What Are The Different Types Of Library In Access Database?

Unnecessary libraries are such a waste of memory. Apart from this, it also originates several issues like slow loading, hinders the process debugging, and many others.

Mainly there are three important libraries of the Access database: VBA, DAO, Access. Out of these three libraries, VBA & Access are in-built and thus they have the highest priority. Nor you can remove any of these built-in libraries from the Access database.

Data Access Objects (DAO): This object model is specifically written for better performance of the Access database. So that it can save your data in a very organized way within the Access tables.

ActiveX Data Objects (ADO): This is the most generic library which is designed for handling up the data from different sources besides the Access tables (SQL Server) and interfaces aside from web-based. Those who all are running the enterprise databases are well familiar with the ADO library.

Microsoft has made this ADO library the default one in Access 2002 and 2000 versions. Whereas, DAO is the default library in Access 2007 and 2003 version.

Here is the complete lists of the library references that are appropriate as per the Access version:

Library name Access Version File Type Library File (default location)

(Visual Basic For Applications)
2010 C:\Program Files\Common Files\Microsoft Shared\vba\vba7\vbe7.dll
2007 C:\Program Files\Common Files\Microsoft Shared\vba\vba6\vbe6.dll

What Problem Arises Due To Access Library Not Registered Error?

If your Access database libraries contain an object with the same name. like ADO and DAO libraries both contain the Recordset object, then the Access database will definitely be stuck whenever the DAO recordset is used.

Well, this issue can be easily resolved by using these tricks:

  • Modify the DAO library’s priority by shifting it over the ADO.
  • Delete the reference of either the DAO or ADO library.
  • Disambiguate each of the single declarations, by simply specifying your intended library
      For example, Dim rs As DAO.Recordset

Situations like data corruption and inconsistencies at the end result in referencing incorrect libraries for the Access version.

Such as Access 97 version uses DAO 3.5 library. Whereas, in Access 2003, 2002, and 2000 version uses DAO 3.6 library whereas the ACEDAO library allows you to use new features for a private JET engine.

How To Fix Access Library Not Registered Error?

1# Re-Register The Library

  • To check which libraries are referenced in the Access project, you need to open the code window by pressing the Ctrl+G
  • Now go to the tool menu and tap to the References tab.

Re-Register The Library

  • Here if you see any library is marked with a “missing” keyword then hit the browse Now search for the right library file.

Note: To help you out in this selection process I have made a list of files that are important for each version of Access libraries.

  • If still, you are unable to get the libraries then immediately re-register it. Press Window + R button from your keyboard and in the opened run dialog box type regsvr32 along with the complete library file path. Like this:

regsvr32 “c:\program files\common files\microsoft shared\dao\dao360.dll”

  • Most of the time it is seen that Access library not resistered error won’t resolve until the library is unregistered and then re-register.

So here is the code that you need to use for unregistering the problem-causing library.

regsvr32 -u “c:\program files\common files\microsoft shared\dao\dao360.dll”

  • After completing the process of unregistering now re-register it with the above-given code.
  • Open your Access database and then once again choose the library reference.

2# Make Registry Settings

  • Close the MS Access application.
  • Press the Window +R button from your keyboard.
  • In the opened Run window you have to type “regedit” and enter the ok button.

  • Search for these locations:
    • HKEY_CLASSES_ROOT
    • Typelib
    • {0006F062-0000-0000-C000-000000000046}
  1. Hit the plus sign this will expand {0006F062-0000-0000-C000-000000000046} option. make a
  2. Within this you will get a folder of “1.0”, choose the “Delete” option.
  3. Hit the “Yes” button as you need to delete the value permanently.
  4. Exit the Registry Editor.

3# Match The Library List

To work around this problem, follow these steps:

  • Go to the Start menu and click the Run button.
  • In the opened run window you have to type the regedit after that hit the OK button.
  • In the Registry Editor, search for the following key.

HKEY_CLASSES_ROOT\TypeLib

  • If the following subkey {91A74EB0-EFA0-482B-B43C-35CFC74B275F} is present and delete it.
  • Close the Registry Editor.
  • Again open the Run window by pressing the window +R button. Type cmd and hit OK button.

  • In the opened command prompt window type the following command and then hit the enter button.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\regtlibv12.exe “C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\dteproperties.tlb”

  • You will get a message regarding the success of registration.
  • Restart your Access database application.

4# Fix The Add-Ins Issue

Another best option to fix Access library not registered error is to find out which add-ins are actually causing the issue. Here is how to resolve this add-in problem in Access.

  • Press the Alt+F11 to open the VBA Editor.
  • From the tool menu select the References tab.

Re-Register The Library

  • In the opened References dialog box you will see the complete list of libraries. From this list, you have to note down which library options are checked.
  • Close the dialog box of References and take an easy exit from the VBA Editor.

Now go to your PC in which you are getting this library not registered error and perform the above steps once you reached in the step 3 you have to match whether both the system is selected with the same libraries or not.

Now close the VBA editor and check whether your Access database is still showing library not registered error or not.

5# Re-Register The Access Database Application

Another option is to re-register the Access application completely. If you don’t know how it is to be done, check out the following steps:

  • Take the complete exit from the Access database applications if it is opened.
  • Go to your system start menu and choose the run option.
  • Now from the opened run dialog box.

If your given path contains any kind of space then put your path within the double-quotes. Here is an example of what you have to enter in the text box.

     “c:\Program Files\Microsoft Office\Office\access.accdb” /regserver

  • Hit the OK button.
