The file d2hlnk16.dll is a linking file used by Doc-To-Help, made by WexTech Systems, Inc.  Doc-To-Help is a program that converts Word Documents to Windows help files.  Because WexTech Systems created this file, it may be an older file.  Doc-To-Help was acquired by ComponentOne and has been updated regularly since then.  This particular file may be from an older version of the program and might not be needed on your machine if you are using the latest version of Doc-To-Help.

When new versions of software are produced, the dynamic link libraries for the software are often updated as well.  In some cases, the files are renamed.  Unless the installation program for the upgrade specifically deletes them, the old files may sit uselessly on your computer.  In some cases, the files are deleted, but the references to them in the registry are not removed.  This can eventually cause errors to pop up.

To fix the errors, run ZookaWare PC Cleaner, the registry cleaner.  We will clean out the old entries in your registry, and make sure your computer is running smoothly again.
