Mostly on newer Windows you can not install anymore the old CD from Kingpin
How to fix that put your cd in the disk.
Copy data1.cab and data1.hdr to location where you want to install Kingpin.
For example C:\Games\Kingpin\
also put i5comp.exe in that directory.
run a Command prompt in that directory (cmd.exe).
Run:
i5comp x data1.cab

After that you can deleted:
i5comp.exe
data1.cab
data1.hdr
