How can I get Silk Performer "What's This" contextual Help to work on Windows Vista or later?

Problem:

How can I get Silk Performer "What's This" contextual Help to work on Windows Vista or later Windows versions?

Resolution:

In Silk Performer it is possible to get information about GUI functionality by right-clicking GUI controls and choosing What's This?. This contextual help does not work on Windows Vista or later Windows versions. This is a known issue related to the fact that the Windows Help program WinHlp32.exe is no longer included with newer Windows versions. To resolve this, download the respective .exe file from the Microsoft Download Center. For more information, see: http://support.microsoft.com/kb/917607.
