ADODB connection

Hello ! 
I would like to access to datas (cells content) inside an excel file without openning it.

I know the solution using "CreateObject("excel.application")" and "EXCELAPP.Workbooks.Open" that opens the Excel file but I don't want to use this solution.
I want to use the solution with ADODB connection.
For this I have a piece of code : 

Sub TestAccessConn()
     Dim objConn As New ADODB.Connection
     Dim objRS As New ADODB.Recordset
     'Should do a connection with excel
    With objConn
         .Provider = "Microsoft.Jet.OLEDB.4.0" 'for 32bit app
        '.Provider = "Microsoft.ACE.OLEDB.12.0" 'for 64 bits app
         .ConnectionString = "Data Source=C:\Users\Olivier\Desktop\excel.xls;"
     End With
     MsgBox objConn.Sheets("Feuil1").cells(1, 1)
End Sub

Usually, I have to install the reference Microsoft ActiveX Data Objects 2.8 Library" in the reference list (just to check) 
But it's not enough. I get the message "The provider has'nt be founded or is not correctly installed"
My windows is windows 7 64 bits 
CorelDraw 2019 is 64 bit but Excel (last version) is 32 bit 
I become mad as I don't find what is wrong.
I donn't know what to use with CorelDraw 2019 (Jet ? or Ace ?)
I tried to install the MSDASQL but it's not working

There are no documentation about the Ado Connection with CorelDraw. 
Is it possible or not as by the past it was ? 
Thank you if you have an idea...
