Our software and Windows Vista and later

 

The only known issues our software had with Windows Vista and later were limited to the programs using help files with the "HLP" file name extension. These problems were resolved as explained below:

Helpfiles with the "HLP" file name extension and Windows Vista and later (Windows 7, Windows Server 2008 ...)

Windows Help (WinHlp32.exe) is a help program that has been included with Microsoft Windows versions starting with Microsoft's Windows 3.1 operating system. The Windows Help program (WinHlp32.exe) is required to display the traditional 32-bit help content files that have the "HLP" file name extension.

Windows Help is deprecated for Windows Vista and the file WinHlp32.exe does not longer ship with this and later Windows operating systems.

To view 32-bit Help files with the "HLP" file name extension in Windows Vista and later operating systems, you will need to download and install WinHlp32.exe from the Microsoft Download Center:

for Windows Server 2008 R2 :

for Windows 7 :

for Windows 8 :

for Windows 8.1 (x86) :

for Windows 8.1 (x64) :
http://www.microsoft.com/downloads/details.aspx?FamilyId=8cc63c95-edb3-4192-8a4a-aa4ce50cac7c
 

These downloads provide the WinHelp32 engine for existing help applications (for more details, see Microsoft Knowledgebase article 917607).
 

Please note that :

1) Only for Windows 8.1 are there x86 (32 bit) and x64 (64 bit) versions of the Windows Help program available;
2) The Windows Help program is not supported in Windows 10, Windows Server 2012 or later versions of Windows Server.


One of the help systems now used by Windows Vista and later that are compatible with previous operating systems down to Windows 98 is HTML Help (help files with the "CHM" file name extension).

A limitation of the HTML Help file system is that opening an HTML help file over the network fails. When displaying documentation in CHM format over the network, the content pane displays a message saying "The page cannot be displayed" or "Action canceled". This behavior is the consequence of a patch that Microsoft released in autumn 2005 in order to reduce security vulnerabilities in the HTML Help system. This is a problem if your application resides on your network and you expect to use the help file located there.

A workaround would be to modify or create the following registry entries (for more details, see Microsoft Knowledgebase article 896054) :

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\HHRestrictions] "MaxAllowedZone"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions] "MaxAllowedZone"=dword:00000001

This step must be performed on every client computer on the network to enable HTML Help.

Modifying the registry could make your computer inoperable. Make sure to back up the registry before you modify it and make sure that you know how to restore the registry if a problem occurs.


The following software, previously using the older 32-bit Help files with the "HLP" file name extension, has been updated to the newer HTML Help file system supported by Windows Vista and later (help files with the "CHM" file name extension):

Vidis
Vidis Lite
M-Minder
Copy-it Lite

(Duax Pro already used HTML help).

If these programs are downloaded from this site they will use the newer HTML help file system (your shareware registration key remains valid).
If older versions are used with the newer operating systems the appropriate WinHlp32.exe file must be downloaded from Microsoft and installed in Windows in order to access the program's helpfile.
