This method works beautifully. It uses the Install Shield Cabinet File Viewer
iscab.exe command line utility as an alternative to the iscabvu.exe file extraction method (assumed above).

Assume an initial directory structure as follows:
%Downloads%\InstallShield_Cabinet_File_Viewer
%Downloads%\silent_hunter_5_1.02_eu
(where %Downloads% can be anything, any path)

CD to your "silent_hunter_5_1.02_eu\Disk1" directory

Run this command
=============
..\..\InstallShield_Cabinet_File_Viewer\iscab data1.cab -i"allmyfiles.ini" -lx

Make a copy of allmyfiles.ini --> allmyfiles_edit.ini
delete everything in this file except for the following:

[ISCAB Info]
Product=ISCAB
Version=2.0

[Game]
File40="sh5.exe"

Run this command
===========
..\..\InstallShield_Cabinet_File_Viewer\iscab data1.cab -i"allmyfiles_edit.ini" -x

You should find the file sh5.exe extracted in the current directory
Done.
