Provider cannot be found error

I am trying to use use VBA to sync data to and from excel. When I try to sync from the database I get "Run-Time error 3706 Provider cannot be found. It may not be properly installed." I'm not sure what this error means. I've looked online for solutions and have just further confused myself. I'm not sure if I need to change my VBA or what.

Here is the code I'm using:

Sub SyncFromDatabase()
LastLocalChange = Sheet1.Range("B11").Value
    DbFile = Sheet1.Range("SharedFolder").Value

    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set objFile = objFSO.GetFile(DbFile)
If objFile.DateLastModified > LastLocalChange Then
    Set objConnection = CreateObject("ADODB.Connection")
    Set objRecordset = CreateObject("ADODB.Recordset")
    objConnection.Open "Provider=MicrosoftACE.12.0;" & "Data Source=" & Sheet1.Range("SharedFolder").Value & ";Extended Properties=""Excel 12.0 Xml;HDR=Yes;IMEX=0"";"
    objRecordset.Open "Select*FROM [CustDb$]", objConnection
    Sheet2.Range("A2").CopyFromRecordset objRecordset
    objRecordset.Close
    RefreshContactTable
    End If


End Sub

The error is occurring in the obj.Connection.Open section of the VBA. If any one can please help I would be so thankful!
