Semantic error(s) in DCL file. See acad.dce for details.

Cause: One of the standard AutoCAD support file search paths has been removed.

Solution: Manually restore the missing support file search path. The location of the support path depends upon the version of AutoCAD you are running.

All of the support paths are located in your AppData folder. The location of this folder depends upon the operating system you are running.

One simple way to find it is to open Windows Explorer, type %APPDATA% into the address bar, and press ENTER. Make sure the percent signs are included when you type it in. The current folder will be changed to the AppData\Roaming folder.

You can also locate it manually: C:\Users\<User Name>\AppData\Roaming

The AutoCAD support folder will be located in that folder.

  • AutoCAD 2008: …\Autodesk\AutoCAD 2008\R17.1\enu\support

  • AutoCAD 2019: …\Autodesk\AutoCAD 2019\R23.0\enu\support

Once you have located the folder, you can add it back to the AutoCAD support file search path using the following steps:

  1. Copy the filepath from the Windows Explorer address bar.
  2. In AutoCAD, type OPTIONS at the command line.
  3. Select the Files tab.

  5. Press the Add button.
  6. Paste the filepath into the field provided and press ENTER.
    • You can also press the Browse button and browse to the file.
