In AutoCAD 2013, Autodesk officially classified VBA as a legacy component. While they provided a 64-bit VBA 7.1 engine, they required users to install it manually. This decoupling meant that running standard .dvb project files on a 64-bit machine would throw missing component errors until the correct module was applied.

事实上，Microsoft早已停止了对VBA的开发和支持。Autodesk从AutoCAD 2010版本开始就不再默认集成VBA，并明确鼓励开发者转向更现代的.NET API（使用C#或VB.NET）。2016年之后的AutoCAD版本虽然仍可单独安装VBA模块，但VBA已被视为一种“维护模式”的技术，不再获得新的功能和性能优化。 autocad 2013 vba module 64-bit
安装64位VBA模块的步骤非常简单，按照以下顺序操作即可：
If you want to optimize your environment further, please let me know: The exact you are using. In AutoCAD 2013, Autodesk officially classified VBA as
To secure your automation tools for future upgrades, consider migrating your VBA projects into or C# utilizing the AutoCAD .NET API. Alternatively, lightweight tasks can be rewritten using modern Visual LISP , which enjoys native, out-of-the-box support across all modern 64-bit AutoCAD deployments.

For long-term system stability, larger development projects should look toward migrating source code to modern execution environments supported natively by AutoCAD:
When declaring External API calls (Windows API) in a 64-bit environment, you must use the PtrSafe keyword. This tells the compiler that the function is safe to execute in a 64-bit environment. Declare Function GetActiveWindow Lib "user32" () As Long Use code with caution. 64-Bit Compliant Syntax:
This error occurs if the installer cannot locate the specific registry keys for AutoCAD 2013. It happens when mixing languages (e.g., trying to install an English VBA enabler on a German AutoCAD installation) or if you are running a vertical product like AutoCAD Mechanical without the base version profile active. Ensure your module language pack matches your primary software language. Failed Digital Signature Verification
Repair your primary AutoCAD 2013 installation via the Windows Control Panel, then reinstall the VBA module using Administrator privileges.
