Com o VBA, encontre a versão do driver MySQL ODBC instalado no Windows

Você pode encontrá-lo no registro em

HKEY_LOCAL_MACHINE\SOFTWARE\
    ODBC\ODBCINST.INI\
    ODBC Drivers\MySQL ODBC 3.51 Driver


 HKEY_LOCAL_MACHINE\SOFTWARE\
    ODBC\ODBCINST.INI\
    ODBC Drivers\MySQL ODBC 5.1 Driver

Usando as informações encontradas aqui , você pode obtê-lo usando o código abaixo (eu testei no Access 97)

Private Sub Command0_Click()    
    If RegKeyExists("HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\
                                 ODBC Drivers\MySQL ODBC 3.51 Driver") Then
        MsgBox "3.51"
    ElseIf RegKeyExists("HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\
                                 ODBC Drivers\MySQL ODBC 5.1 Driver") Then
        MsgBox "5.1"
    Else
        MsgBox "None"
    End If
End Sub


'returns True if the registry key i_RegKey was found
'and False if not
Function RegKeyExists(i_RegKey As String) As Boolean
    Dim myWS As Object

    On Error GoTo ErrorHandler
    'access Windows scripting
    Set myWS = CreateObject("WScript.Shell")
    'try to read the registry key
    myWS.RegRead i_RegKey
    'key was found
    RegKeyExists = True
    Exit Function

ErrorHandler:
  'key was not found
  RegKeyExists = False
End Function
