How to install silently Microsoft VBA module for Inventor or ... - Autodesk

To write robust code that works across both 32-bit and 64-bit deployments of AutoCAD, implement conditional compilation arguments using the VBA7 or Win64 compiler constants: Because Autodesk has updated its download portals over

: Always embed On Error GoTo routines within your subroutines to catch unhandled database exceptions without crashing the host CAD application.

If the installation succeeded, the Microsoft Visual Basic for Applications development window will open seamlessly. Migrating Legacy 32-Bit Macros to 64-Bit VBA Close Running Applications Choose a destination folder to

Even after installing the module, your macros might crash. The reason?

To bridge this gap, Autodesk implemented a clever workaround: When you run VBA in a 64-bit environment (AutoCAD 2013 64-bit plus the 64-bit VBA module), to host the VBA engine. It then marshals COM calls between the main 64-bit AutoCAD application and this separate 32-bit VBA process.

A 32-bit application can only address a maximum of 4 Gigabytes (GB) of RAM. In contrast, a 64-bit application can address up to 16 Terabytes (TB) of RAM. Because a 64-bit application cannot directly load 32-bit dynamic link libraries (DLLs) into its memory space, legacy 32-bit VBA modules could not run natively inside the 64-bit process of AutoCAD 2013.

To reduce the core installer file size and encourage developers to adopt VB.NET or C#, Autodesk stopped embedding the VBA IDE directly inside AutoCAD. For users who rely on legacy .dvb macros, installing the external 64-bit VBA module remains necessary to run their custom tools. Technical Differences: 32-Bit vs. 64-Bit VBA
