PtrSafe Asserts that a Declare statement is targeted for 64-bit systems. Required on 64-bits. so try to add it to the declaration like :

Private Declare PtrSafe Function GetDesktopWindow Lib "user32" () As Long
Private Declare PtrSafe Function ShellExecute Lib "shell32"

Open in new window


For both version you could use a conditional declaration like :

#If Vba7 Then 
Private Declare PtrSafe Function ... 
#Else 
Private Declare Function ... 
#EndIf
