Epson Perfection 4870 Installer crashes. I have installed this without a problem an a different machine under Tiger. I am wondering If I can not get the installer to work would I be able to place the individual files in their respectable directories to somehow manually install them?

System:
Kalyway 10.5.2 AMD
AMD X2 5000 2.4GHz
Asus M2N SLI Deluxe
4gb DDR800 XMS2
PNY 7600GT 256mb
