AUTOCAD - Fixing corrupt user profiles

If Autocad runs ok in a different profile, you probably have a corrupted user profile and just need to back up any customizations, then do a reset.

Login using a good profile:

BACKUP:
1. START>All Programs>Autodesk>AutoCAD 2015>Migrate custom settings>Export AutoCAD 2015 settings.
2. Click the EXPORT button.
3. In the Export custom settings dialog box, select a location to save the ZIP file created by the program.


Login using corrupt profile:

RESET:
START>All Programs>Autodesk>AutoCAD <version> 2015>Reset Settings to Default

RESTORE:
START>All Programs>Autodesk>AutoCAD 2015>Migrate custom settings>Import AutoCAD 2015 settings.
Point the program to the file you created previously.

That should restore functionality.

3. If you are having licensing issues, you can remove the licensing storage file as well. If you are not dealing with licensing errors, removing this file may be unnecessary. Remove the Trusted Storage file (Licensing) located in these areas:

• C:\ProgramData\FLEXnet\adskflex_########_tsf.data
• C:\ProgramData\FLEXnet\adskflex_########_tsf.data.backup

4. Delete any residual Program Files from these locations:

• C:\Program Files\Autodesk\
• C:\ProgramData\Autodesk\
• C:\Program Files (x86)\Autodesk\
• C:\Users\All Users\Autodesk\
• C:\Users\**YOUR USERID**\AppData\Roaming\Autodesk\
• C:\Users\**YOUR USERID**\AppData\Local\Autodesk\

The program folders should be clearly named.

5. Clean out your TEMP files:
   1. Click the Windows Start button.
   2. In the Run box type %TEMP% and press Enter
   3. Highlight and delete all files. Ignore any files in use
