The d2hlnk32.dll file is part of Doc-To-Help created by WexTech Systems, Inc.  Doc-To-Help is an application that turns Word Documents into Windows help files.  WexTech Systems created this particular file, which was the original developer of the program.  The program is now owned by ComponentOne and is regularly updated.  This file may be part of an older version of Doc-To-Help and could be a leftover from an upgrade if you are using the most current version of Doc-To-Help.

The Windows registry contains entries that point to every part of every program on your computer.  If the registry is not updated properly when a program is updated, the registry may have extra entries.  New software versions usually include updated dll files, and in this case the dll files may have been renamed.  A registry error involving this file could have several possible causes.  Rather than hunt down the problem manually, trust ZookaWare PC Cleaner, the registry cleaner, to find and fix the error for you.
