Thanks, after I made that adjustment, I got a "type mismatch" compile error. However, if also adjust the 64bit code to not have "LongPtr" (only Long) then it seems to work on both 32 bit and 64 bit (as follows). Is this OK? 

#If VBA7 Then
     ' 64 Bit API
    Private Declare PtrSafe Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
    Private Declare PtrSafe Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
#Else
     
     ' 32 bit API
    Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
    Private Declare Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
#End If
