Access Database Engine Error

Hi,

I have created a Power BI Report which reads an email from the Outlook, extracts the Excel attachment and performs the query function on the excel data.  New emails are sent every day and Power BI Report reads the latest email and updates the report.

All these works perfectly fine on PowerBI Desktop app.  However, when I schedule the auto refresh setting through PowerBI service, the auto refresh throws the following error:

• Processing errorExcel Workbook: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. The 64-bit version of the Access Database Engine 2010 Access Database Engine OLEDB provider may be required to read this type of file. To download the client software, visit the following site: https://go.microsoft.com/fwlink/?LinkID=285987.

Just to be sure, initially the same error was shown by PowerBI Desktop App.  Hence I downloaded the client software as suggested in the error and the refresh option in the Desktop App works fine.  However, the PowerBI service throws the same error while auto refreshing.

Any idea why this might happen?
