The AutoCAD 2015 VBA module is a 64-bit software component that is compatible with the 64-bit version of AutoCAD 2015. The 64-bit version of the VBA module is required to work with the 64-bit version of AutoCAD 2015, as it provides a more secure and stable environment for running custom applications.
Before AutoCAD 2014, even when AutoCAD itself was a 64‑bit application, its VBA engine remained 32‑bit. This was possible because AutoCAD launched the VBA 6.3 engine in a and marshalled COM calls between the two processes. This approach meant that even on a 64‑bit machine, your VBA macros were still running in a 32‑bit sandbox.
