Strange Help File Error

[Don]

Getting the following error when trying to access help
from the start menu...

mkmsitstore:c:\winnt\help\windows.chm Microsoft HTML
Help Exe

Tried re-registering after finding tech document on site
and it had no effect. Any help would be appreciated. In
addition, other program help files also are not working
and will display as grayed out help screen or simply bring
up nothing at all. Thanks to anyone with information.

Don,

Getting the following error when trying to access help
from the start menu...

mkmsitstore:c:\winnt\help\windows.chm Microsoft HTML
Help Exe

I'd recommend that you run MJ's Help Diagnostics to check that the
HTML Help viewer components are properly installed and registered on
your machine. You can get this tool from here:

http://helpware.net/downloads/index.htm#MJs

(The only section of the MJ's Help Report that is relevant to your
problem is the one headed "HTML Help Run-time Components".)

Here are some other things to try:

1) If you've yet to install Service Pack 4 for Windows 2000, apply
Microsoft Critical Update 811630, which is available from here:

http://support.microsoft.com/?kbid=811630

This will install the latest versions of the HTML Help viewer
components.

2) If you *have* installed Service Pack 4, unregister the HTML Help
ActiveX control and then re-register it by running the following two
commands from a command prompt:

regsvr32 /u <drive>:\winnt\system32\hhctrl.ocx
regsvr32 <drive>:\winnt\system32\hhctrl.ocx

3) Delete or rename the file hh.dat, which you should find in this
directory:

\Documents and Settings\%username%\Application Data\Microsoft\HTML
Help

The hh.dat file stores user-specific information on all the HTML Help
files on your system (favourite topics, search history, etc.), and can
cause the files to misbehave if it has somehow been corrupted. Windows
will create a new version of hh.dat when you next open any .chm file.

4) Empty your Temporary Internet Files directory. A full TIF directory
can cause HTML Help files to misbehave.
