From the INSTALL.txt that's in my folder...
1) Obtain version 2.83 or later of the popular FSUIPC module from
http://www.schiratti.com/dowson.html
FSUIPC is a .dll module installed into the MODULES directory/folder under your FS2002 program directory/folder. It requires no user interaction unless you utilize its advanced features. Installing the .dll file is enough.
IF FSUIPC DOES NOT WORK ON YOUR SYSTEM, THEN ARRESTORCABLES WILL NOT WORK.
2) Create a folder such as
...\Program Files\ArrestorCables\
or
...\FS2002\ArrestorCables\
Make sure the following files are in the ArrCab installation folder:
INSTALL.TXT (this file)
ArrestorCables.exe
ArrestorCables.dat
ArrestorCables.INI
ArrCab25Abacus.txt
Catapult.wav
CableCatch.wav
DamageElectricalSystem.wav
DamageFarExplosion.wav
DamageNearExplosion.wav
DamageRadio.wav
KNHK cables day.jpg
KNHK cables night.jpg
(NOTE: the sound files are played by ArrCab, not by FS, so DO NOT move them to the FS sound folder)
3) Create a convenient shortcut to ArrestorCables.exe.
