Your macro references components from older versions of AutoCAD (e.g., AutoCAD 2012 Type Library ).
VBA 7.1 (included in AutoCAD 2015) introduces the LongPtr variable type. LongPtr automatically scales: it acts as a 32-bit Long on 32-bit systems and a 64-bit LongLong on 64-bit systems. Windows API Declarations ( Declare Statements)
Ensure third-party Active X controls ( .ocx files) used in user forms are compiled for 64-bit, as 64-bit VBA cannot load 32-bit binaries. Deployment and Automation Commands
Choose a temporary folder to extract the installation files (the default is usually C:\Autodesk ). autocad 2015 vba module 64-bit
Any variable that stores a window handle (hWnd), a file handle, or a memory pointer must be converted from Long to LongPtr . The LongPtr type dynamically scales to 32 bits on 32-bit systems and 64 bits on 64-bit systems, ensuring cross-platform stability. Troubleshooting Common Errors "VBA is not supported in this version of AutoCAD"
Once complete, restart AutoCAD 2015 to initialize the VBA environment. 4. Verifying the Installation To ensure the VBA module was installed correctly: Open AutoCAD 2015. Type VBAIDE in the command line and press Enter. The Visual Basic Editor window should open.
For years, Visual Basic for Applications (VBA) has been a cornerstone of AutoCAD customization, allowing users to automate repetitive tasks, build custom tools, and enhance productivity through powerful macros. However, with the release of AutoCAD 2015, the landscape for VBA developers shifted significantly. While the raw power of VBA remained, the underlying engine evolved from a 32‑bit component to a native 64‑bit one, marking a fundamental change in how VBA interacts with the modern AutoCAD environment.

Ensure that your installed version of AutoCAD 2015 is the 64-bit edition. You can check this by typing ABOUT in the AutoCAD command line and looking at the product specifications. 2. Download the Official Installer
According to Microsoft Q&A , AutoCAD 2015 can work on Windows 10 with the KB3081448 update or later. Ensure your Windows is updated. 3. Missing References ( .dvb Errors)

If your office uses a mixed environment (some users on legacy 32-bit AutoCAD, others on 64-bit AutoCAD 2015), use conditional compilation constants to ensure the code runs everywhere:
Before installing the AutoCAD 2015 VBA module, ensure the following:
