MORE INFORMATION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

After you install Visio 2003 SP3, you can disable the use of .dwg files in Visio 2003. You may want to disable .dwg files in Visio 2003 to improve the security of Visio 2003 files.

When you disable .dwg files, the following behavior occurs:
 * AutoCAD Drawing (*.dwg; *.dxf) does not appear in the Files of type box in the Open dialog box
 * CAD Drawing is disabled on the Insert menu.
