In the module below, I get a "Could not find installable ISAM" error on the
tdf.refresh link.
The NewConnection refers to a valid database/table.

My References include VBA, Access 9.0 Object Library, DAO 3.6, OLE and VBA
Extensibility 5.

Do I need some other reference or ??

Dim db As DAO.Database, tdf As DAO.TableDef
Dim ThisDB As String, ThisPath As String, NewConnection As String

'Get current folder
ThisDB = CurrentDb.Name
ThisPath = Left(ThisDB, InStrRev(ThisDB, "\") - 1)

Set db = CurrentDb
Set tdf = db.TableDefs("tPreferences")

NewConnection = "DATABASE=" & ThisPath & "\" &
"DataTransferUtility4.mdb;TABLE=tPreferences"

tdf.Connect = NewConnection
tdf.RefreshLink
