AutoCAD Help File Will not reference in Options
Posted by - NA - on 13 April 2011 02:14 PM

Go to Options>Profiles tab and set other profile to be Current and restart Civil 3D. Do you still get the same error? If other profile is working OK, then you may only be having an issue with your profile. 

Then go to Options>Files tab and under Help and Miscellaneous File Names, set Help location to C:\Program Files\Autodesk\AutoCAD Civil 3D 2011\Help\acad181.chm (use copy/paste)


If that does not work use the following steps:

  1. Start>Run and type REGEDIT
  2. Then browse to the following key: HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R18.1\ACAD-9000:409\Profiles\AutoCAD\General
  3. Make sure the ACADHELP set to C:\Program Files\Autodesk\AutoCAD Civil 3D 2011\Help\acad181.chm
  4. Restart Civil 3D
