The AutoCAD VBA integrated development environment (VBA IDE) needs to be installed to create and execute macros. 
The VBA IDE is not installed with the product; it must be downloaded and installed separately. The following steps outline how to check for and install the VBA IDE as needed: 
- At the AutoCAD Command prompt, enter vbaide. 
If the VBA IDE opens, the VBA IDE is installed. If you receive the message “VBA - Not Installed,” the VBA IDE is not installed. Proceed to step 2 to install the VBA IDE. 
  
- On the VBA - Not Installed message box, click the http://www.autodesk.com/vba-download link, or open a Web browser and browse to the URL. 
 
- Close the message box and then close AutoCAD before proceeding. 
 
- On the Web page, download the appropriate module for the AutoCAD release and platform installed on your workstation. 
 
- Run the installer and follow the instructions that are displayed. 
 
- Launch AutoCAD. 
 
- At the AutoCAD Command prompt, enter vbaide. 
The VBA IDE should open.
