Below are some detail notes of testing Microsoft Compiled Help. It is not
true that all *.CHM files will not work from a net work drive. There are
files from many companies, Microsoft included, that will work from any where.
There are other files from many companies, Microsoft included, that just
plain won't work if IE7 is installed.
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution
Options\hh.ex
What are the options?
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution
Options\hhctrl.ocx
What are the options?
HKLM\Software\Policies\Microsoft\Windows\CurrentVersion\Internet
Settings\ZoneMap\Domains
Should this be set?
There are many files that cannot be opened when IE7 is installed.
IE7 is supposed to allow the processing of all Microsoft HTMP Help files
(*.CHM) on the local C drive.
The following files cannot be opened by double clicking on them.
C:\ProgramFiles\Microsoft Office\Office 12\1033\VBAOWS10.CHM -- Canâ??t access
second frame
C:\UTL\Microsoft\ProcessExp\v11.13\procexp.chm â?? Quietly goes away
The above file was acquired via download on 22nd May, 2008. The extracted
files provide an unreadable *.CHM file.
C:\Program Files\Quest Software\SQL Navigator 5.5\SQLMNTR.CHM Kills
application
C:\Program Files\Quest Software\SQL Navigator 5.5\SQLNAV.CHM Kills application
All of the following files are on network servers. The results vary.
Q\Developers Software Installs\SPS\WindowsSharePointServicesAdmin.chm The
file opens, but Navigation to Webpage was cancelled. This file is blocked.
Q:\DRIVES\MODEM\mohhelp.chm The file opens, but Navigation to Webpage was
cancelled. This file is NOT blocked.
Q\Developers Software Installs\SDKs\adsi25sdk.zip adsi25.chm. This file
works. The file is not blocked. It is even contained within a zip file.
Extracting the file makes no difference.
The pattern continues. There is no absolutely sure pattern.
I see multiple help files in a directory and some work some donâ??t. The
files that donâ??t work, continue not to work, even when they are on the local
C drive.
The inability to move to IE7 is also preventing the move to VISTA.
I have worked with suppliers to get individual files. I have downloaded
them using IE7. I have used a streams tool from Sysinternals to inspect the
files before and after unlocking the files.
I have applied all of the suggestions in various Microsoft knowledge base
articles. We have downloaded and tried HHReg and while an interesting tool
it did not solve one problem.
This is a huge problem and not one of just little tweaks.
There are other Registry Keys not found when is use Sysinternals Process
Monitor to what is going on with hh.exe and hhctrl.ocx
This is a hell of a lot of work for a small organization.
