Autocad 2015 Vba Module 64-bit -

AutoCAD 2015 VBA Module (64-bit) is an optional "VBA Enabler" required to run Visual Basic for Applications macros within the 64-bit version of AutoCAD 2014 or later. Starting with the 2014 release, AutoCAD transitioned to the

engine, which runs as a native 64-bit process if the host AutoCAD software is 64-bit. Autodesk Community, Autodesk Forums, Autodesk Forum 1. Key Technical Changes 64-bit Native Process:

Unlike older versions (2013 and earlier), where VBA remained a 32-bit process even on 64-bit systems, the 2015 module runs natively in 64-bit. VBA 7.1 Engine:

This version is not 100% backward compatible with VB6. You may need to update legacy code, specifically when dealing with 32-bit Windows API calls 32-bit OCX controls , which are no longer supported in this environment.

VBA is no longer included in the default AutoCAD installation media and must be added separately. Access the AutoCAD 2015 VBA Enabler 64-bit directly from Autodesk Support Preparation: Close all running programs, especially AutoCAD. Extraction:

Double-click the downloaded EXE to unzip it to a local folder (typically C:\Autodesk Execution: AutoCAD 2015 VBA Module (64-bit) is an optional

from the extracted folder and follow the on-screen prompts to complete the installation. Verification: Launch AutoCAD and type

at the command prompt. If the Visual Basic Editor opens, the module is correctly installed. 3. Common Compatibility Issues

Why VBA is No Longer Pre-Installed

Starting with AutoCAD 2010, Autodesk began phasing out VBA due to security concerns and the rise of more modern APIs like .NET (C#/VB.NET) and AutoCAD's native AutoLISP. However, recognizing the massive library of legacy VBA macros in the industry, Autodesk continued to support VBA as a free add-on module. Why VBA is No Longer Pre-Installed Starting with

For AutoCAD 2015 64-bit, there is no built-in VBA IDE. If you attempt to run a VBA macro (e.g., using the VBARUN command) or open a .DVB project file, you will receive an error stating that VBA is not installed.

The LongPtr and LongLong Data Types

In 32-bit VBA, memory addresses and handles (like hWnd or object pointers) fit into a 32-bit integer (Long). In 64-bit VBA, these addresses require 64 bits. Microsoft introduced two new data types:

  • LongPtr : A pointer-sized integer. It resolves to Long (32-bit) in 32-bit VBA and LongLong (64-bit) in 64-bit VBA. Use this for Declare statements and API calls.
  • LongLong : A true 64-bit integer. Only available in 64-bit VBA.

Performance & Stability

  • Runs reliably for simple to medium complexity macros.
  • May crash if macros rely on deep recursion or large database operations (less stable than .NET in heavy automation).
  • Works fine on Windows 7/8/10; on Windows 11, occasional compatibility mode tweaks needed.

5. Common Issues & Fixes

| Issue | Likely Fix | |-------|-------------| | VBAIDE unknown command | VBA enabler not installed | | Compile error: PtrSafe not found | Using wrong Office VBA (need VBA 7.0+). AutoCAD 2015 includes it. | | API declares crash AutoCAD | Replace Long → LongPtr + add PtrSafe | | VBA project won't load | Unblock file (right-click → Properties → Unblock) |
