Autocad 2015 Vba Module - 64-bit

Since AutoCAD 2014, the software uses the VBA 7.1 engine, which supports both 32-bit and 64-bit environments. However, the VBA module is no longer included in the default installation and must be added separately as a "VBA Enabler". 1. Installation & Setup

To enable VBA for AutoCAD 2015 64-bit, you must download and install the specific VBA Enabler module:

Download: Locate the AutoCAD 2015 VBA module 64-bit from the official Autodesk Support site.

Install: Close all programs, run the downloaded .exe, and follow the on-screen prompts to extract and install the module.

Verify: Open AutoCAD 2015 and type VBAIDE at the command prompt. If installed correctly, the Visual Basic Editor will launch. 2. Key Commands

Manage your projects directly from the AutoCAD command line: Download the Microsoft VBA Module for AutoCAD - Autodesk autocad 2015 vba module 64-bit

Final Checklist for Success

The 64-bit VBA module is not glamorous, but it is functional. With this guide, you have the knowledge to resurrect your old macros and keep your AutoCAD 2015 environment productive for years to come.

Title: Technical Overview and Implementation Guide: AutoCAD 2015 VBA Module 64-bit

The #If VBA7 Directive

To write code that works in both 32-bit and 64-bit VBA environments, you must use conditional compilation. Since AutoCAD 2014, the software uses the VBA 7

Example: Declaring a Windows API function to get the AutoCAD window handle

#If VBA7 Then
    ' 64-bit compatible declaration
    Declare PtrSafe Function GetParent Lib "user32" (ByVal hWnd As LongPtr) As LongPtr
#Else
    ' Legacy 32-bit declaration
    Declare Function GetParent Lib "user32" (ByVal hWnd As Long) As Long
#End If

Notice the PtrSafe keyword. This is mandatory for any Declare statement in 64-bit VBA. Without it, your module will throw a compile error.

3. 64-bit Specifics – Declare Statements

In 64-bit AutoCAD, all API declarations must use PtrSafe and pointer types.

3.2 Security Implications

The 64-bit VBA module adheres to stricter security protocols introduced in later Windows Operating Systems. This includes compliance with User Account Control (UAC) and Data Execution Prevention (DEP), which can affect how macros interact with the file system and Windows API.

If you are starting a new automation project, consider migrating away from VBA: Final Checklist for Success

Issue: "VBA module failed to initialize" on startup

Solution: This occurs when the acvba.arx file fails to load. Repair the VBA Enabler installation. Also, check for conflicting third-party ARX applications.

Conclusion: Is AutoCAD 2015 64-bit VBA Right for You in 2024?

As of today, AutoCAD 2015 is long out of mainstream support (support ended in 2018). However, many manufacturing, engineering, and architecture firms still run it due to certified hardware or legacy vertical products (e.g., Civil 3D 2015, AutoCAD Electrical 2015).

The AutoCAD 2015 VBA Module 64-bit 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.

Important Technical Considerations for 64-bit VBA

While the module allows VBA to run, there are critical differences between 32-bit and 64-bit environments:
