Question

I am running an ASP.NET C# application on .NET 4.0 framework using VS2010 on a Win 7 machine. Within my code I want to link Excel file with “DataTable” object. ie I want to access the data within Excel file and store it in DataTable object. So I used the following code snippet:

_

_connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\"" + excelFile + "\";Extended Properties='Excel 8.0; HDR=NO; IMEX=1'";
        }

DataTable table = new DataTable();
            OleDbCommand command = new OleDbCommand();
            command.Connection = new OleDbConnection(_connectionString);
            command.CommandType = CommandType.Text;
            command.CommandText = "select * from [NameOFExcelSheet$A1:D20]";  // Want to read the Excel sheet. The name of Excel sheet is "NameOfExcelSheet". Wan to read the celles in the range A1 and D20.

            OleDbDataAdapter adapter = new OleDbDataAdapter();
            adapter.SelectCommand = command;
            adapter.Fill(table);  // EXCEPTION OCCURS IN THIS LINE. 

I installed the exe available at the link http://www.microsoft.com/downloads/en/confirmation.aspx?FamilyID=7554F536-8C28-4598-9B72-EF94E038C891&displaylang=en

But still I am gettin the same exception msg while running my code.
The exception that I am getting is “The ‘Microsoft.ACE.OLEDB.12.0’ provider is not registered on the local machine”

PLz help me with this.

THANKS IN ADVANCE.

You’re probably on 64bit Windows and installed a 32bit driver. Either switch to 32bit compilation or source a 64bit driver.
