Question: Why am I having problems
getting the application help to work on certain workstations?
Answer: ExpressMaintenance uses
the Microsoft HTML help system for it's application help. If you
have trouble running the application help, the problem can be one of
several things.
1. Microsoft HTML Help Not Installed
Microsoft HTML help is included with most
releases of Microsoft operating systems. Some older releases did
not include it. You can download the installation program directly
from our website -

2. Permission Issue
ExpressMaintenance spawns the HTML Help
program and opens the help file (ExpressMaintenance.chm) from the
ExpressTech folder where the Maintenance.exe file resides. There
may be a permission issue on your network preventing the opening of that
file or spawning the application. Check with your network
administrator and have him attempt to open the ExpressMaintenance.chm
file from your workstation.
3. Microsoft Security Hotfix Problem
Microsoft recently released a security
hotfix update that creates problems with running the HTML help from
within other applications and across a network. There is a easy fix for this.
Below are instructions for correcting the problem caused by the hotfix.
Problem -
Cannot view Express Maintenance
help files after you install Microsoft Windows Hotfix (Security
Update 896358)
|
Issue: |
After opening a CHM documentation
file, a topic may not appear when you click a link from the
Table of Contents. Also, when you try to use a Universal Naming
Convention (UNC) path to open a .CHM file that exists on a
network shared folder, topics in the .chm file may not appear.
|
|
Reason: |
You are using Microsoft Windows
XP and have installed
Security Update 896358
from Microsoft, which prevents the features of some web
applications and HTML help systems from working properly. |
|
Solution: |
Please read and follow the instructions
under Method 2 described in
this technical note from the Microsoft
Knowledge Base. You will need
to perform some changes to your registry.
Caution:
If you use Registry Editor incorrectly, you may cause serious
problems that may require you to reinstall your operating
system. |
Beginning with release 6.1.3.7,
ExpressMaintenance attempts to automatically create the registry entries
when the user selects to run the help. However, this may fail
because the user may not have permission to edit the registry. No
error message is generated. You may need to manually create the
registry entries using the following instructions.
1. In ExpressMaintenance, click on
Utilities / View Connection Properties.
2. Find and note the Exe Path from which
the Maintenance.exe is running.
3. Exit ExpressMaintenance.
4. Click on Start / Run and type "regedit"
in the Open prompt and click OK.
5. Using the registry tree, locate the
registry key HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / HTML Help /
1.x.
6. Right click on 1.x and enter the new
key of "ItssRestrictions".
7. Right click on the ItssRestrictions
key and enter a new DWord entry. Name the entry "MaxAllowedZone".
8. Right click on the MaxAllowedZone
entry and Modify the value to 3.
9. Right click on the ItssRestrictions
key and enter a new String entry. Name the entry "UrlAllowList".
10. Right click on the UrlAllowList entry
and Modify the string value to be the Exe Path noted above in step 2.
11. Check to make sure the entries are
correct and then exit regedit.
When finished, the registry should look
similiar to the screen shot below except that the path should be your
actual network path.
This will allow the HTML help system to
run when executed from ExpressMaintenance assuming there are no
permission or firewall issues preventing otherwise.
