Once extraction completes, the main Autodesk installation wizard will launch automatically. Accept the licensing terms and click .
Any variable that stores a window handle (hWnd), a file handle, or a memory pointer must be converted from Long to LongPtr . The LongPtr type dynamically scales to 32 bits on 32-bit systems and 64 bits on 64-bit systems, ensuring cross-platform stability. Troubleshooting Common Errors "VBA is not supported in this version of AutoCAD"
Exit AutoCAD 2015 and any open Microsoft Office programs to prevent file conflicts during installation. 3. Run the Installer
Declare PtrSafe Function GetModuleHandle Lib "kernel32" (ByVal lpModuleName As String) As LongPtr
Many legacy macros rely on external 32-bit ActiveX controls ( .ocx files), such as old common dialog boxes or tree-view components. 64-bit VBA cannot load 32-bit ActiveX controls. autocad 2015 vba module 64-bit
This occurs if the structural COM components of AutoCAD fail to register correctly within the Windows registry during installation.
Prior to 2010, the Visual Basic for Applications (VBA) engine was built directly into AutoCAD. However, as Microsoft shifted focus to .NET and Autodesk moved toward a more modular 64-bit architecture, VBA was removed from the standard installation. The Change
The official installer file names typically appear as:
Run older scripts developed in 32-bit environments, though some code modification may be required for 64-bit compatibility. System Requirements for 64-bit Installation The LongPtr type dynamically scales to 32 bits
Open the OPTIONS dialog box in AutoCAD, navigate to the Files tab, and add the directory containing your .dvb files to the Trusted Locations list. Alternatively, adjust the SECURELOAD system variable to control safety thresholds. If you need to update a specific macro file, tell me: What error message or code line is failing? What action does the macro perform? Should it run automatically on startup ?
Right-click the downloaded executable and select .
The advantage was that you could use existing 32‑bit OCX controls and Type Libraries without modification. However, this cross‑process communication came with a major performance penalty: in 64‑bit AutoCAD than they did in a 32‑bit environment.
Open the VBAIDE , use Ctrl+F to search for Declare , and update the syntax to include PtrSafe alongside the appropriate LongPtr variable types. 2. Missing Active X Controls on UserForms 3. Security Warning: Macros Blocked
The transition to 64-bit computing environments brought immense processing power to CAD workstations, allowing engineers and architects to handle massive datasets and complex 3D models. However, this architectural shift introduced significant hurdles for legacy automation tools. One of the most common disruptions occurred with Visual Basic for Applications (VBA). If you are running a 64-bit version of Autodesk AutoCAD 2015 and attempting to execute macro workflows, you have likely encountered errors indicating that VBA is not installed or that your .dvb projects cannot be opened.
Because the VBA module is not bundled with the initial AutoCAD installer, it must be downloaded and installed separately. 1. Download the Module
: Close AutoCAD. Open the Windows Command Prompt as an Administrator and type: acad.exe /regserver (Note: You may need to provide the full file path to your acad.exe directory). 3. Security Warning: Macros Blocked
