Thanks for contacting the Intellibot support team.

To fix the Data Reader | ReadFromExcel | AutxDataReader | Microsoft.ACE.OLEDB.12.0 error:

You need to download and install a set of components that can be used to facilitate transfer of data between 2010 Microsoft Office System files and non-Microsoft Office applications.

Please click the link below:

      Microsoft Access Database Engine 2010 Redistributable


Note: There are multiple files available for this download. Once you click on the "Download" button, you will be prompted to select the files you need.

  • Select AccessDatabaseEngine.exe


This download will install a set of components that facilitate the transfer of data between existing Microsoft Office files such as Microsoft Office Access 2010 (*.mdb and *.accdb) files and Microsoft Office Excel 2010 (*.xls, *.xlsx, and *.xlsb) files to other data sources such as Microsoft SQL Server. Connectivity to existing text files is also supported. ODBC and OLEDB drivers are installed for application developers to use in developing their applications with connectivity to Office file formats. 


Installation Instructions:

Note: Before installing this download, you must first remove any previous versions of the Access Database Engine from your computer by using Add/Remove Programs in the Control Panel. 

To install this download:

  2. Double-click the AccessDatabaseEngine.exe program file on your hard disk to start the setup program.

Hi Ankit,

Thanks for contacting the Intellibot Support team.

It appears that you are using Windows 32-bit Operating System and hence you need to download the Access Database Engine for the same.

However, let us verify the OS version prior to installation by following the steps below:

Step1: In Search field next to Windows icon, type PC.

Step 2: Right click on “This PC” and select “Properties”.

Step3: Check for Windows version against “System Type”.

Step4: If your system type is 32-bit Operating System, you can download AccessDatabaseEngine.exe file by accessing the URL below:

Follow the instructions on the screen to complete the installation.

Note: In case of 64-bit Operating System, AccessDatabaseEngine_X64. exe may be downloaded and installed.

Step 5:  Once the installation is done, save your work and restart Intellibot Studio.

Have a nice day.

Thank you.

I have 64 bit O365 installed, can i read from this version of excel without these components being installed?

If you want to use DataReader/DataWriter components then you need to install these components (Access DataBase Engine), if not you can use our Excel/Word connector to interact with Excel/Word.

Thanks & Regards,

Intellibot Support.
