Typenunverträglichkeit bei Umstellung auf 64bit

Hallo

wir haben einen Access-Applikation die auf 32bit und 64bit Systemen laufen, bis auf eine Typenunverträglichkeit und ich weiß nicht, was ich da noch ändern könnte. Hier ist das Modul (die Fehlerzeile habe ich fett markiert, ziemlich weit unten).

Option Compare Database
Option Explicit

Private Const WM_COMMAND = &H111
Private Const WM_LBUTTONUP = &H202

Private Const MF_SEPARATOR = &H800&
Private Const MF_ENABLED = &H0&
Private Const MF_GRAYED = &H1&
Private Const MF_CHECKED = &H8&
Private Const MF_MENUBARBREAK = &H20&

Private Const TPM_LEFTALIGN = &H0&

und hier ist der Aufruf

Private Sub aufrufPopup_Click()

    Dim strPop As String

    #If Win64 Then        
        Dim lngRet As LongPtr
    #Else
        Dim lngRet As Long        
    #End If
 
    strPop = "test 1|test 2|test 3|..."
    ' Starte das Menü
    lngRet = DoPopup(strPop)
    Select Case lngRet
        Case 1
       [...]
        Case Else
            Exit Sub
End Select

Hat jemand Lust, mal darüber zu schauen?

Lieben Dank im voraus. 

Liebe Grüße, die Luzie!
