Here Mudassar Ahmed Khan has explained how to resolve the error The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. This error occurs when you try to make use of Excel 2007 or higher or Access 2007 or higher files using OLEDB connection in C# or VB.Net.

This happens only for Office 2007 or higher as it requires use of OLEDB ACE drivers for connection which do not come by default in Windows and hence we need to install them in order to get rid of this error.
