Cracking Excel VBA Password 64-bit and 32-bit

I’ve built upon Đức Thanh Nguyễn’s fantastic answer to allow this method to work with 64-bit versions of Excel. I’m running Excel 2010 64-Bit on 64-Bit Windows 7.

  1. Open the file(s) that contain your locked VBA Projects.
  2. Create a new xlsm file and store this code in Module1
    Option Explicit
    
    Private Const PAGE_EXECUTE_READWRITE = &H40
    
    Private Declare PtrSafe Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _
    (Destination As LongPtr, Source As LongPtr, ByVal Length As LongPtr)
    
    Private Declare PtrSafe Function VirtualProtect Lib "kernel32" (lpAddress As LongPtr, _
    ByVal dwSize As LongPtr, ByVal flNewProtect As LongPtr, lpflOldProtect As LongPtr) As LongPtr
    
    Private Declare PtrSafe Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As LongPtr
    
    Private Declare PtrSafe Function GetProcAddress Lib "kernel32" (ByVal hModule As LongPtr, _
    ByVal lpProcName As String) As LongPtr
    
    Private Declare PtrSafe Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As LongPtr, _
    ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _
    ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer
    
    Dim HookBytes(0 To 5) As Byte
    Dim OriginBytes(0 To 5) As Byte
    Dim pFunc As LongPtr
    Dim Flag As Boolean
    
    Private Function GetPtr(ByVal Value As LongPtr) As LongPtr
        GetPtr = Value
    End Function
    
    Public Sub RecoverBytes()
        If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 6
    End Sub
    
    Public Function Hook() As Boolean
        Dim TmpBytes(0 To 5) As Byte
        Dim p As LongPtr
        Dim OriginProtect As LongPtr
    
        Hook = False
    
        pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA")
    
    
        If VirtualProtect(ByVal pFunc, 6, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then
    
            MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, 6
            If TmpBytes(0) <> &H68 Then
    
                MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 6
    
                p = GetPtr(AddressOf MyDialogBoxParam)
    
                HookBytes(0) = &H68
                MoveMemory ByVal VarPtr(HookBytes(1)), ByVal VarPtr(p), 4
                HookBytes(5) = &HC3
    
                MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 6
                Flag = True
                Hook = True
            End If
        End If
    End Function
    
    Private Function MyDialogBoxParam(ByVal hInstance As LongPtr, _
    ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _
    ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer
    
        If pTemplateName = 4070 Then
            MyDialogBoxParam = 1
        Else
            RecoverBytes
            MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, _
                       hWndParent, lpDialogFunc, dwInitParam)
            Hook
        End If
    End Function
  3. Paste this code in Module2 and run it
    Sub unprotected()
        If Hook Then
            MsgBox "VBA Project is unprotected!", vbInformation, "*****"
        End If
    End Sub

DISCLAIMER This worked for me and I have documented it here in the hope it will help someone out.I have not fully tested it. Please be sure to save all open files before proceeding with this option.
