AutoCAD DWG File "Open With" Context Menu

When multiple versions of AutoCAD/Civil 3D are installed, the DWG file 'Open with' context menu shows as 'AtuoCAD Application' to all of them, it is hard to know which 'AutoCAD Application' is the one will be used, this can be solved by making a small change in registry:

  • Run 'Regedit' and open registry;
  • Find the key:
    HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\Shell\MuiCache\
  • Under this key, there are several string values with 'acad.exe' and named with installation path, change their value to a proper name;
  • Close 'Registry' editor.

(Edit registry with care)
