VIGO 5.9 – VIGO tools, help is not working

Help for the majority of the VIGO tools was created in Windows Help format .hlp, which requires a feature not included in various versions of Windows*.
However, you can download a program that makes it possible to view Help created in the old Windows Help format. When the help is opened, an error screen is displayed. Follow the instructions to download and install WinHlp32.exe.

* Microsoft removed the legacy Windows Help .hlp file viewer, winhlp32.exe, from Windows Vista, Windows 7, Windows Server 2008 and 2008 R2. But Microsoft has released an add-on that will restore the .hlp file viewer.
