The supported Windows OS depends on the loader version.

[Help display of loader software]
The help of the loader software is not displayed on Windows 7, 8, and 8.1 by default.
It uses the 32-bit help file with the '*.hlp' extension, which is not supported by Windows 7 and 8 by default.
Download and install 'WinHlp32.exe' from the Microsoft website according to your OS.
Note that you cannot display the help of the loader on Windows 10 since no 32-bit help file is provided by Microsoft.
