On computers that are running with Windows Vista or Windows Server 2008, you may be unable to open Help files that require the Windows Help (WinHlp32.exe) program. This article discusses a download that resolves this problem.

Introduction
Ever since Windows 3.1, Microsoft included the Windows Help program (WinHlp32.exe) with new releases. WinHlp32.exe is used to view 32-bit Help files that have the “.hlp” file name extension. Starting with the release of Windows Vista and Windows Server 2008, Microsoft has decided to no longer include WinHlp32.exe as a component of the Windows operating system. Microsoft made this decision because WinHlp32.exe has not had a major update for many years, and it does not meet Microsoft’s standards for all new Microsoft programs. Microsoft realizes that this may cause some difficulties for customers who want to upgrade to Windows Vista or to Windows Server 2008 but still rely on 32-bit “.hlp” files. Therefore, Microsoft is making WinHlp32.exe available as a download from the Microsoft Download Center.

System Requirements
Supported Operating Systems: Windows Vista; Windows Vista Business; Windows Vista Business 64-bit edition; Windows Vista Business N; Windows Vista Enterprise; Windows Vista Enterprise 64-bit edition; Windows Vista Home Basic; Windows Vista Home Basic 64-bit edition; Windows Vista Home Basic N; Windows Vista Home Premium; Windows Vista Home Premium 64-bit edition; Windows Vista Starter; Windows Vista Starter N; Windows Vista Ultimate; Windows Vista Ultimate 64-bit edition

The Controller Area Network (CAN) was originally developed for automotive applications. It is nowadays a bus system which is widely used in Train, Industry and Building projects.
This bus system allows a very efficient and cost effective networking of modules over a long distance. The CAN hardware and software protocol secure a very stable communication suitable for hard environment projects with high safety requirements.
This “very stable communication” is usually depending on the “work quality” such as the respect of “rules” during the implementation of the CAN network.

CAN malfunctions are often caused by improper use of the bus terminating resistors, by wrong bitrates for the used cable lengths or by a poor cabling.
After years of experience based on different projects in the Train business, the Selectron Systems engineers acquired a huge “Know-How” concerning the implementation of those CAN networks.
In order to help you being efficient in the cabling of your network, those engineers wrote a guideline based on their experience and described the different concepts and points to take care of in such an implementation.
This guideline is available by request at the following email address: support@selectron.ch

Don’t hesitate to ask your questions, the Selectron Systems engineer will be glad to share their knowledge.
