The is a bridge—a way to keep legacy automation alive on modern Windows 10/11 64-bit systems. It works reliably once you update your Declare statements and purge 32-bit dependencies.
Once extraction completes, the main Autodesk installation wizard will launch automatically. Accept the licensing terms and click .
AutoCAD 2015 operates natively as a 64-bit application on modern Windows architecture. Standard 32-bit VBA environments cannot interface directly with a 64-bit host application due to memory addressing mismatches.
AutoCAD 2015 is quite old and may encounter issues on newer operating systems.
To enable VBA scripting in your 64-bit version of AutoCAD 2015, follow these precise deployment steps: 1. Verify Your System Architecture autocad 2015 vba module 64-bit
In a 64-bit environment, the architecture of your operating system, AutoCAD installation, and the VBA module must align perfectly. Running AutoCAD 2015 64-bit means you cannot use standard 32-bit VBA installers. You must specifically deploy the 64-bit module to enable the VBAIDE (Visual Basic for Applications Integrated Development Environment) and VBALOAD commands. Step-by-Step Installation Guide
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 (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.
: Using the AutoCAD ActiveX Automation Interface to communicate with drawing entities, data, and system commands.
The AutoCAD 2015 VBA (Visual Basic for Applications) module is a 64-bit software component that enables developers to create custom applications and automate tasks within AutoCAD 2015. Here's an overview of the topic: The is a bridge—a way to keep legacy
When dealing with memory addresses or window handles (HWND), change the Long data type to LongPtr .
This works identically in 32-bit and 64-bit AutoCAD 2015 because it uses AutoCAD’s object model, not Windows API.
This module will not work with 32-bit AutoCAD or other versions like 2014 or 2016.
Starting with AutoCAD 2010, Autodesk began phasing out VBA in favor of more robust, secure, and modern programming interfaces, specifically the .NET Framework (VB.NET, C#) and ObjectARX. Because Microsoft initially delayed the development of a native, stable 64-bit VBA runtime engine, Autodesk made the strategic decision to exclude VBA from the standard out-of-the-box AutoCAD installation.

Simply installing the 64-bit module is not enough. Your old code written in a 32-bit environment (AutoCAD 2007 or earlier) will likely break. This is the most misunderstood aspect of the transition.
Any Declare statements for Windows API functions must include the PtrSafe keyword.
End Sub
On a 64-bit system, LongPtr compiles as a 64-bit integer to safely hold memory addresses and pointers. The PtrSafe Keyword
