Generic Icons Displaying for AutoCAD Files in Windows Explorer and Mac Finder

When working with AutoCAD files, encountering generic or unrecognized icons in Windows Explorer or Mac Finder can be a frustrating experience. This issue, where file formats like DWG, DWT, or DWF appear blank or with the wrong software logo, can also prevent files from opening correctly when double-clicked. This article provides comprehensive solutions for resolving these icon display problems.

Understanding the Issue

The problem typically arises when the file type association for AutoCAD files is broken or incorrectly set. This means that Windows or macOS no longer recognizes which application should open these files by default. Consequently, instead of displaying the correct AutoCAD icon, the operating system shows a generic placeholder, and double-clicking the file might fail to launch AutoCAD, open a different application, or produce an error message. It’s important to note that AutoCAD backup files (.bak) are not program-associated and are expected to display a blank icon.

Solutions for Windows Users

Several methods can be employed to fix the incorrect icon display for AutoCAD files on Windows:

Re-associate File Extensions

The most common solution is to re-establish the correct file association.

1. Right-click on an affected AutoCAD file (e.g., a .dwg file) in Windows File Explorer.
2. Select ‘Properties’.
3. In the properties window, click the ‘Change’ button next to the “Opens with:” field.
4. From the list of applications, select ‘AutoCAD DWG Launcher’.
5. Check the box for ‘Always use this app to open DWG files’ and click ‘Set default’.
6. Click ‘OK’ in the subsequent windows to apply the changes.

Force a File Association Refresh

If simply re-associating doesn’t resolve the issue, you can try forcing a refresh of file associations:

1. Right-click an affected file and select ‘Open With’ > ‘Choose another app’.
2. Select ‘AutoCAD Application’ for your installed AutoCAD version and check ‘Always use this app to open DWG files’. Click ‘OK’.
3. Repeat steps 1 and 2, but this time select ‘AutoCAD DWG Launcher’. Ensure the ‘Always use this app to open DWG files’ box is checked, and click ‘OK’.

Editing the Registry (Advanced Users)

For persistent issues, especially with .DST files, registry edits may be necessary. Proceed with caution when editing the Windows Registry, as incorrect modifications can cause system instability.

1. Press WINDOWS-R, type REGEDIT, and press Enter.
2. Navigate to and delete the following registry keys if they exist:
   • HKEY_CLASSES_ROOT.dwg
   • HKEY_CURRENT_USERSoftwareClasses.dwg
   • HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts.dwg
   • HKEY_CURRENT_USERSoftwareRoamingOpenWithFileExts.dwg
3. Close the Registry Editor and reboot your PC.
4. Upon restarting AutoCAD, a dialog box titled “AutoCAD – DWG Association” should appear. Select ‘Always reassociate DWG files with AutoCAD (recommended)’. If this dialog does not appear, close and restart AutoCAD again.

Alternatively, after deleting the registry keys, you can manually re-associate the file type:

1. In Windows Explorer, double-click a DWG file.
2. When prompted to choose an application, click ‘More apps’, then ‘Look for another app on this PC’.
3. Navigate to and select C:Program FilesCommon FilesAutodesk SharedAcShellExAcLauncher.exe.

Changing the Default Icon via Registry

To manually change the icon displayed for DWG files:

1. Open Registry Editor (REGEDIT).
2. Navigate to HKEY_CLASSES_ROOT.dwg. Note the value data for the (Default) entry (e.g., AutoCAD.Drawing.24).
3. Navigate to the key corresponding to that file type (e.g., HKEY_CLASSES_ROOTAutoCAD.Drawing.24).
4. Locate the DefaultIcon subkey. This contains the path to the icon file.
5. Modify the (Default) value within DefaultIcon to the desired icon file path (e.g., C:Program FilesAutodeskAutoCAD 2024en-USacadficn.dll,49). Ensure you use the correct path for your installed AutoCAD version.
6. Save the changes and restart your computer or log out/in for the changes to take effect.

Solutions for macOS Users

On macOS, re-associating file extensions can also resolve this issue:

1. Right-click on an affected AutoCAD file.
2. Select ‘Get Info’.
3. Under the ‘Open With:’ section, choose the desired AutoCAD application from the dropdown menu.
4. Click ‘Change All’ to apply this association to all files of that type.
5. Click ‘Continue’ to confirm.

Corrupt Windows Profile

In rare cases, a corrupt Windows user profile can interfere with program associations. Creating a new user account in Windows, signing into it, and testing AutoCAD can help determine if this is the underlying cause.

By following these troubleshooting steps, users can effectively restore the correct icons for their AutoCAD files and ensure seamless file opening within Windows Explorer and Mac Finder.
