Issue
AutoCAD Profile has corrupted and will not load so therefore has to be recreated
Solution
As an initial step, please follow the guide in this Autodesk Knowledgebase Article
If this does not fix the issue, please follow the steps below:
- With AutoCAD closed, run Registry Editor from the Start Menu.
- Go to HKEY_CURRENT_USER\Software\Autodesk\AutoCAD<version>. For AutoCAD 2026, this would be 'Autodesk>AutoCAD>R26.0>ACAD-A101.409' For Civil and other versions the code will be different.
- Rename the key adding the suffix "OLD", e.g. >R26.0>ACAD-A101.409OLD'
- Once this has been completed, close Registry editor and open Windows Explorer, browse to %AppData% and \Local\Autodesk\AutoCAD <version>
- Rename the AutoCAD folder to AutoCAD <version>old
- After this, if you rerun AutoCAD, the profile will recreate and the software should load correctly.
