I needed a solution in order to get help working for Delphi Studio Architect on Windows 10.
Komeil's install.cmd file didn't work as is (its pre Win10) so I simply modified it.
Unpack the download (Install.cmd, winhlp32.exe, winhlp32.exe.mui) to a new directory. Edit the install.cmd and add the following two lines to the 'settings' section:

set WindowsVersion=7
goto :BypassVersionError
