- Broken Shortcut or Incorrect Working Directory: Launching AutoCAD from a shortcut where the "Start in" path is invalid.
- Damaged Installation: A failed update, interrupted installation, or missing system files.
- Permission Issues: AutoCAD does not have "Read & Execute" permissions for the Support folder.
- .NET Framework or C++ Redistributable Corruption: Since AutoCAD relies heavily on Microsoft frameworks, corruption here can trigger DLL loading errors.
- Partial Uninstall of Previous Versions: Leftover registry keys from AutoCAD 2019 or 2020 conflicting with the new 2021 installation.
Solution 7: Fix Registry Errors
To fix registry errors:
- Open the Registry Editor (Press the Windows key + R and type
regedit).
- Navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD 2021\R14\Profiles
- Check for any errors or inconsistencies in the registry entries.
