Troubleshooting SOLIDWORKS Help (CHM) Files

This article will review troubleshooting procedures for viewing offline SOLIDWORKS help files. These can be accessed under the "?" on the top right of the SOLIDWORKS window. If you want to access help files offline, please deselect "Use Web Help" under this menu.

Accessing the Offline help menu

If you prefer to use online web help, please navigate to https://help.solidworks.com/. This article will only list troubleshooting processes to fix offline help files, not online. Users who are using a system that does not have access to the internet can use these "CHM" (Microsoft Compiled HTML Help) files.

Offline help files window

While accessing offline help files, you may encounter one of the following problems.

  • Memory errors
  • Content displayed with incorrect formatting
  • XML/HTML code is displayed instead of the actual content
  • No content is displayed.

Please follow the processes below to resolve these problems.

Troubleshooting the Help Files

The most likely cause of any of the problems listed above is the "itss.dll" file. Registering this DLL manually should allow the Help files to open without issue. To register this file:

  1. Open the command prompt (Start > Type "cmd").
  2. Type the following command: regsvr32 C:\WINDOWS\system32\itss.dll
  3. Press Enter. A message should be returned saying that the operation succeeded.

If that does not help resolve the issue, please try the following commands to register other DLLs.

  • regsvr32 %systemroot%\system32\hhctrl.ocx
  • regsvr32 %systemroot%\system32\ITSS.DLL
  • regsvr32 %systemroot%\system32\ITIRCL.DLL
  • regsvr32 %systemroot%\system32\HHACTIVEX.DLL

Help File Location

If you need to open the Help files to test them outside of SOLIDWORKS, I have listed the location below. You can find the sldworks.chm file along with other CHM help files for other products.

C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\lang\english\sldworks.chm
