While the VBA Module allowed code to run, it was not a flawless panacea. The transition to 64-bit often exposed underlying coding habits that were sloppy in 32-bit environments but fatal in 64-bit ones. Specifically, the module required the installation of the "VBA Object Model Enabler." Without this, some API calls would fail because the pointers and handles in a 64-bit environment are twice the size of their 32-bit counterparts.

However, the module was clearly labeled as an "unsupported" or "as-is" technology. It was a stopgap. Autodesk used this transition to strongly encourage developers to migrate their VBA projects to VB.NET or C#, utilizing the more robust .NET API. While the VBA module allowed the old engine to run, it could not leverage the full potential of the 64-bit architecture in the way a compiled .NET plugin could. It was a lifeline, not an upgrade.
