Autocad 2015 Vba Module 64-bit

If your VBA code uses Windows API functions (e.g., FindWindow, GetTickCount), you must update all Declare statements with the PtrSafe keyword. Example:

Incorrect for 64-bit:

Declare Function GetTickCount Lib "kernel32" () As Long

Correct for 64-bit:

Declare PtrSafe Function GetTickCount Lib "kernel32" () As Long

Let's walk through a real migration scenario.

Visual Basic for Applications (VBA) served as the primary customization and automation language for AutoCAD for nearly two decades. However, Microsoft ceased further development of VBA around 2007, leading Autodesk to transition towards .NET API and Microsoft Visual Studio as the primary development platform.

Despite this shift, a vast library of legacy VBA macros remains in use across the AEC (Architecture, Engineering, and Construction) and manufacturing industries. To support this legacy ecosystem while adhering to modern 64-bit security and memory standards, Autodesk releases the VBA Enabler (or Module) as a separate download. For AutoCAD 2015 running on 64-bit operating systems, this module is not merely an add-on but a compatibility bridge requiring specific architectural considerations.
