For AutoCAD 2013, VBA is with this module. For newer AutoCAD versions (2015+), you would need a separate VBA module per release. Consider migrating to .NET (C#/VB.NET) or AutoLISP if you’re writing new automation.

AutoCAD 2013 uses VBA 6 , which is a 32-bit engine. Even when installed on 64-bit AutoCAD, it runs as an "out-of-process" 32-bit application.
