Problems with excel connection string

I have the following snippet of code that makes connection to Excel, but 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 file Microsoft Access Database Engine 2010 Redistributable that was to correct this error and still contained returning this exception.
