Autocad 2015 Vba Module 64-bit

In 32-bit VBA, memory pointers and handles were stored in 32-bit integers (Long data type). In a 64-bit environment, pointers are 64-bit integers. Storing a 64-bit pointer in a 32-bit Long variable results in data truncation and overflow errors.

In 64-bit VBA, you must modify your Declare statements to be compatible with 64-bit address spaces. This is achieved using the PtrSafe attribute and the LongPtr data type.

| Issue | Solution | |-------|----------| | "VBA module not installed" even after running installer | Re-run installer as Administrator. Check that antivirus didn't block DLL registration. | | "Compile error: The code in this project must be updated for use on 64-bit systems" | Add PtrSafe to all API Declares and replace Long handles with LongPtr . | | VBAIDE opens but macros crash | Ensure no 32-bit OCX references are in the project. Recompile the VBA project. |

: This allowed users with legacy macros to keep working without forcing the bulky, older VBA engine onto users who had moved to .NET or AutoLISP. 2. The 64-Bit Leap By the time AutoCAD 2015 arrived, 64-bit operating systems were the standard. The Module autocad 2015 vba module 64-bit

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.

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.

The AutoCAD 2015 VBA Module for 64-bit systems is an essential utility for organizations maintaining legacy automation workflows. It successfully bridges the gap between 32-bit legacy code and modern 64-bit hardware. However, it requires diligent management regarding API declarations and pointer types to prevent runtime errors. IT Managers and CAD Developers must recognize that while the module provides backward compatibility, it represents a deprecated technology path, and strategic planning for migration to .NET is imperative for long-term stability. In 32-bit VBA, memory pointers and handles were

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).

While the 2015 VBA module provides a reliable stopgap for running older code, relying heavily on VBA is a long-term risk. Autodesk has officially deprecated VBA, meaning it is no longer actively developed or optimized.

On a 64-bit system, LongPtr compiles as a 64-bit integer to safely hold memory addresses and pointers. The PtrSafe Keyword

Re-run the installer explicitly as an administrator. If you are operating in an enterprise environment, ensure your IT permissions allow the registration of the VBA COM objects. Security Controls and Blocked Macros

Migrating VBA projects to the 64-bit module in AutoCAD 2015 requires specific updates to your code. The most common compatibility issues are:

The "story" of the AutoCAD 2015 VBA Module (64-bit) is a classic tale of a legacy technology being kept on life support to bridge the gap between old-school automation and modern computing.

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
