    This occurred for me after upgrading from a local install of Office 13 to Office 16 through the Office 365 program. I was getting this exception: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

    I was not able to find a way to install the driver through the office 365 install process.

    I had to install https://www.microsoft.com/en-us/download/details.aspx?id=13255 - the x64 version did not solve the issue, had to use the 32bit version.

    My connection string in App.config

        
    

    Code using it:

                var excelConnectionString = ConfigurationSettings.GetExcelConnection(fileLocation);
                var dataTable = new DataTable();
    
                using (var excelConnection = new OleDbConnection(excelConnectionString))
                {
                    excelConnection.Open();
                    var dataAdapter = new OleDbDataAdapter("SELECT * FROM [Users$]", excelConnection);
                    dataAdapter.Fill(dataTable);
                    excelConnection.Close();
                }
                Console.WriteLine("OpenExcelFile: File successfully opened:" + fileLocation);
                return dataTable;
