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
: Reinstall the VBA module from the original AutoCAD 2015 installation media or deployment image. You may need to install the English version of VBA (e.g., VBA71033.msi for some localized versions of AutoCAD).

AutoCAD 2015 continues this trend, relying on the for its VBA capabilities. While this offers much better performance, it also introduces strict compatibility rules : any DLL, OCX control, or Type Library loaded into the VBA environment must now be 64‑bit as well. There is no way to load a 32‑bit component into a 64‑bit process. This is the single most important concept to understand when working with the AutoCAD 2015 64‑bit VBA module. autocad 2015 vba module 64-bit
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:

Unlike older versions of AutoCAD, VBA is not installed by default in AutoCAD 2015. It must be deployed separately.
If you do not use any Windows API calls and only use the AutoCAD Object Model (e.g., ThisDrawing.ModelSpace ), you likely do not need to change your code at all—provided you recompile it.
