Resolving user specific issues by resetting AutoCAD Civil 3D 2011

Issue

You have a situation where a single user is experiencing an issue with a particular command or setting.  When another user logs onto the same machine, they do not experience the same issue.

Solution

One of the easiest and quickest ways to resolve the issue for this particular user is to reset the AutoCAD Civil 3D 2011 settings for that user.  To do this, follow these steps:

Important: Make sure you back up any customized Civil 3D 2011 files before you implement the following procedure.

1. Log on to the computer as that user.
2. On the Start menu (Windows), click Run.
3. In the Run dialog box, enter regedit.
4. In the Registry Editor, browse to the following key and delete it:
   
   HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R18.1\ACAD-9000:409
    
5. Close the Registry Editor.
6. Using Windows Explorer, browse to and delete the following user's application folders:
   
   For Windows Vista and Windows 7
   
   C:\Users\<user>\AppData\Roaming\Autodesk\C3D 2011 C:\Users\<user>\AppData\Local\Autodesk\C3D 2011
   For Windows XP
   
   C:\Documents and Settings\<user name>\Application Data\Autodesk\C3D 2011
   C:\Documents and Settings\<user name>\Local Settings\Application Data\Autodesk\C3D 2011
    
7. Start AutoCAD Civil 3D. This will initiate the secondary installer, re-creating the deleted files and folders.
