Problems with the excel connection string

I have the following code snippet that connects to Excel, however it returns me the error:

string sFileXLSX = ConfigurationManager.AppSettings["ExportPerformanceEntrega"];
string strConnXLSX = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" + sFileXLSX + "';Extended Properties=Excel 12.0;";

using (OleDbConnection conn = new OleDbConnection(strConnXLSX))
{
    //SQL para fazer o Delete

    string strSQL = "DELETE FROM [Base Entregue1$]";
    //Criando o OleDbCommand com o SQL e a conexão
    OleDbCommand cmd = new OleDbCommand(strSQL, conn);
    //Abrindo a conexão
    conn.Open();
    //Executando o Delete
    cmd.ExecuteNonQuery();
    //Fechando a conexão
    conn.Close();
}

  

Microsoft.ACE.OLEDB.12.0 'provider is not registered on the local   machine

But I already installed the Microsoft Access Database Engine 2010 Redistributable file that was meant to fix this error and even though it contained this exception .
