Declare Function GetFrequency Lib "kernel32" (lpFrequency As Currency) As Long Use code with caution.
Declare PtrSafe Function GetFrequency Lib "kernel32" (lpFrequency As Currency) As LongPtr Use code with caution. Key Rules for Migration:
Before installing, ensure that AutoCAD 2015 is fully installed and closed.
If your legacy code calls external Windows DLL files, standard 32-bit Declare statements will crash in a 64-bit environment. You must update these statements using the PtrSafe attribute and the LongPtr data type.
With the release of AutoCAD 2015, Autodesk continued the architectural shift from 32-bit to 64-bit computing environments. A significant consequence of this shift was the decoupling of Visual Basic for Applications (VBA) from the core installation package. This paper provides a detailed technical analysis of the AutoCAD 2015 VBA Module for 64-bit systems. It explores the architectural necessity of the module, the installation process, the critical migration challenges regarding API pointer safety, and best practices for legacy code maintenance.

The installer will ask for a location to unzip the installation files. The default location is usually acceptable.
user wants a long article about "autocad 2015 vba module 64-bit". I need to provide comprehensive coverage. The search plan includes four main topics: the official VBA module, 64-bit compatibility, installation and troubleshooting, and development best practices. I'll execute the searches as outlined. search results for the first round are in. I have information on downloading the VBA module from various sources, including CAD tips and a blog. I also have results on compatibility issues, installation problems, and the PtrSafe keyword. The official Autodesk download page might be difficult to find directly. I need to proceed with the second round of searches for development best practices and alternative sources. have gathered information from various sources. Now I need to synthesize this into a comprehensive article. The article should cover the importance of the VBA module, where to find it, installation steps, 64-bit compatibility issues, best practices for development, troubleshooting, and alternatives. I will structure the article with an introduction, sections on downloading, installing, compatibility, development best practices, troubleshooting, and a conclusion. I'll cite the relevant sources. move from 32-bit to 64-bit computing created a significant transition period for many software ecosystems, and AutoCAD's VBA (Visual Basic for Applications) environment was no exception. For AutoCAD 2015, the shift to a native 64-bit VBA engine marked a fundamental change that directly impacts how developers write, maintain, and execute their automation scripts.
While VBA is supported in AutoCAD 2015, it is important to look toward the future. Autodesk has stated that VBA will be removed in a future release of AutoCAD. For this reason, it is wise to plan for a potential migration. The most strategic path is to begin porting your VBA code to VB.NET using the .NET API. This ensures your custom tools will remain functional and supported for years to come, providing a future-proof customization environment.
Historically, AutoCAD included the VBA engine by default in 32-bit versions. The transition to 64-bit computing required a fundamental architecture shift. Architecture and Memory Address Space
