The d2hlink.dll file is a linking file in Doc-To-Help by WexTech Systems, Inc.  Doc-To-Help takes a Word Document and coverts it to a Windows help file.  This particular dynamic link library is an integral part of the program.  However, it may be helpful to note that ComponentOne later acquired Doc-To-Help, and that this might be a legacy file.  If you are running a current version of the program, this file may not be needed on your machine, and could just be hanging around causing problems.

To find out if this file is needed, and if it is where it should be, you can run a registry cleaner.  The Windows registry is a database of all the files all the applications on your computer need to run.  Sometimes an entry is left in the registry even when the program that needs it is removed.  To keep your computer running smoothly, you should clean your registry periodically.  ZookaWare PC Cleaner is a registry cleaner with a 60-day money-back guarantee.  Let ZookaWare PC Cleaner do the work and have a fast computer again.
