vba to create a .accde file with 64-bit Access 2013

I successfully use the following code for 32-bit Access:

Public Function ConvertToAccde(SourceDB As String, TargetDB As String) As Boolean
    Dim accessApplication As Access.Application
   
    ConvertToAccde = False
    Set accessApplication = New Access.Application
    With accessApplication
        .SysCmd 603, SourceDB, TargetDB
    End With
    ConvertToAccde = True
    Set accessApplication = Nothing
Exit Function

However, this code does not work for 64-bit Access 2013. It hangs on the .SysCmd line and never exits.

Suggestions please.
