Solving the Access 2010 automation error library not registered dilemma with simple steps



For instance, you may see a message that says "object library not registered," and be completely lost as to what it means. In this case, it is helpful to understand how Excel works with external programs.


Excel comes with an amazing number of libraries, but not all of them are accessible at the same time. A library is only available after it has been "registered" with Excel. If the library is not registered, then Excel cannot use it and the macros in the add-in cannot use it. The result: an error message.




access 2010 automation error library not registered



This article is to share with you one issue which i faced with this. Once I uninstalled 2013 then in Excel Macro, wherever I was using Excel.Application Library, It started throwing the below error: Automation error. Library not registered


One way to resolve this error and not see the issue again is to install the Microsoft.ACE.OLEDB.12.0.NET Client Library. This can be found in the Office 2010 runtime for the OleDB driver (64-bit version).


Some users have reported that when running VBA in an Excel chart or trying to generate a Macro in Excel documents, an error message popped up saying: Runtime error 1004. And then they find themselves cannot access the Excel files. If you have the same encounter as these users, this post is the right place for you. You can find both the reasons and the corresponding solutions of this error code on this page.


  • Alternatively, you can find outlook.exe in the default installation folder: C:\Program Files\Microsoft Office\Office version. Where Office version is Office15 if you are using Office 2013, Office14 for Office 2010 and so on.Right-click on OUTLOOK.EXE, and then click Properties.

  • Switch to the Compatibility tab and be sure to clear the "Run this program in compatibility mode for" check box.

  • Click OK and try to start Outlook.

If you still cannot open the Outlook window and the same "Cannot start Microsoft Office Outlook" error persists, try to restore the previous version of the PST file. Of course, in this case some of your recent emails and appointments will be lost, but it seems to be a better alternative than no Outlook at all. So, right click on the Outlook.pst file and select Restore Previous Versions.Create a new Outlook profileIf neither repairing nor restoring the Outlook.pst file worked, you can create a new mail profile in order to see if it solves the problem. If it does, then you can copy your current Outlook data file (.pst or .ost) from the broken mail profile to the newly created one.


Another error that may occur in the Exchange server environment is related to a missing default gateway setup. I'm not really sure what it actually means, but fortunately for us Microsoft has an explanation and automatic fix for Outlook 2007 and 2010. You can download it from this page.


Thanks Svetlana for this excellent write up. Recently, I encountered "Unable to display the folder...." error in my Outlook 2010 and your article helped me a lot. Now, my outlook application is working fine!
