When I try to access the SolidWorks help file (Help\SolidWorks Help Topics), the help file opens. The contents tab displays normally. When I click on either the index or the search tab, the are completly empty. When I try to search, I get the "No topics found" message. I have tried to copy the help file from another users computer, but have had no luck fixing the issue. Any insight would be appreciated.

Thanks in advance.

Correct Answer
Here is what the problem was:

SolidWorks may become unstable because the system cannot open .chm files. The SolidWorks help files are .chm (compiled HTML) files. To open .chm files please ensure that HHCTRL.OCX, ITSS.DLL and ITIRCL.DLL have been registered. These files can be found in the Windows\System32 directory.

To manually register a file, open a command prompt (Start -> Run -> "CMD")
and type the following

regsvr32 %systemroot%\system32\hhctrl.ocx
(the above example would register hhctrl.ocx)

A message will appear if the registration has been successful.
