Problem Loading Acadres.dll Resource File !!top!! May 2026

That error message—“problem loading acadres.dll resource file”—is a classic AutoCAD startup issue, usually popping up right when the application launches. It’s a great topic for a blog post because it’s frustrating, cryptic, and surprisingly common across multiple versions (from AutoCAD 2007 to 2024).

Instructions:

  1. Close all Autodesk products completely.
  2. Press Windows Key + R to open the Run dialog box.
  3. Type %appdata% and press Enter. This opens the Roaming folder.
  4. Navigate to: Autodesk\AutoCAD 20XX\RXX.X\enu\Support (Note: 20XX is your version year, and RXX.X is the release number. For example, AutoCAD 2024 is usually R24.3).
  5. Go up one level to the folder that contains the Support folder. You are now in a folder named after your version, e.g., C:\Users\[YourName]\AppData\Roaming\Autodesk\AutoCAD 2024\R24.3\enu\
  6. Look for a folder called Profile or files like acad.CUIX and laststate.CUIX.
  7. Do not delete anything yet. Rename the enu folder to enu.old.
  8. Also go to %localappdata% (paste this into Run).
  9. Navigate to Autodesk\AutoCAD 20XX\RXX.X\ and rename the enu folder here to enu.old as well.
