A: Yes. The modules are installed into different registry hives and different AutoCAD versions. They do not conflict. Before installing, audit your existing VBA projects
Before installing, audit your existing VBA projects. Update any Declare statements, remove 32-bit OCX dependencies, and digitally sign your macros. With these steps, your automation will run reliably on modern 64-bit hardware, often faster and more capable than ever before. Introduction: The 64-Bit Dilemma For decades, AutoCAD users
Introduction: The 64-Bit Dilemma For decades, AutoCAD users have relied on Visual Basic for Applications (VBA) to automate repetitive tasks, create custom workflows, and build powerful design tools directly within the CAD environment. However, a major shift occurred with the release of AutoCAD 2012 and 2013: the move to a true 64-bit application.
