problems when importing Excel file into MVC C #

I have the following code in the controller to import data from an Excel file:

public ActionResult importarExcel()
    {
        var retorno = 0;
        for (int i = 0; i < Request.Files.Count; i++)
        {
            var fileuploader = Request.Files[i];
            if (fileuploader.ContentLength > 0)
            {
                string Foldername;
                string Extension = System.IO.Path.GetExtension(fileuploader.FileName);
                string filename = Path.GetFileName(fileuploader.FileName.ToString());
                if (Extension == ".XLS" || Extension == ".XLSX" || Extension == ".xls" || Extension == ".xlsx")
                {

                    Foldername = Server.MapPath("~/Importados/");

                    fileuploader.SaveAs(Foldername + filename.ToString());

                    String conStr = "";
                    switch (Extension)
                    {
                        case ".xls": //Excel 97-03
                            conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" +
                            "Data Source=" + Foldername + "//" + filename + ";" +
                            "Extended Properties=Excel 8.0;";
                            break;

                        case ".xlsx": //Excel 07
                            conStr = "Provider=Microsoft.ACE.OLEDB.12.0;" +
                           "Data Source=" + Foldername + "//" + filename + ";" +
                           "Extended Properties=Excel 8.0;";
                            break;
                    }
                    OleDbConnection oconn = new OleDbConnection();
                    oconn.ConnectionString = conStr;

                    OleDbCommand ocmd = new OleDbCommand("select * from [Sheet1$]", oconn);
                    oconn.Open();
                    OleDbDataReader odr = ocmd.ExecuteReader();
                    string partida = "";
                    string Description1 = "";
                    string Quantity1 = "";
                    string OriginalPrice1 = "";
                    string Image1 = "";
                    string Shape; string Carat; string Certificate;
                    while (odr.Read())
                    {
                        partida = valid(odr, 0);
                        Description1 = valid(odr, 1);
                        Quantity1 = valid(odr, 2);
                        OriginalPrice1 = valid(odr, 3);
                        Image1 = valid(odr, 4);
                        Shape = valid(odr, 5);
                        Carat = valid(odr, 6);
                        Certificate = valid(odr, 7);

                        // you will get row by value
                    }

                }

            }
        }
        return Json(retorno);
    }

   protected string valid(OleDbDataReader myreader, int stval)//if any columns are found null then they are replaced by zero
    {
        object val = myreader[stval];
        if (val != DBNull.Value)
            return val.ToString();
        else
            return Convert.ToString(0);
    }

But it turns out that when I try to open the connection on the line oconn.Open () after the OleDbCommand, I get the following error:

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

The file I try to import in an excel file of office 2016.

If anyone knows anything, your help is appreciated. Thank you in advance.
