intel rapid storage not runnig

hi i have a dell inspiron 1420 laptop with 965M chipset board. i've dual boot ( XP-SP2 & Vista HP). i followed the

prcedure given by you to change from ATA to AHCI mode and it worked very smoothly.Thank You Very Much.

but i've a problem i installed intel rapid stroage Technology Version 9.6.0.1014 in XP and Vista. when i run XP

there is no problem application is runnig smoothely, but when i ren Vista HP an error is displaying at the system

tray icon " application is not Running", when i try to mannully run the program then it is working, but system is

not shutting down when i put off the system, power LED is glowing continuosly. evey time i am doing forced shutdown

by pressing power button. i unistall this version and install the old version 7.0.0.1020, then application is

running smoothely and shut down ploblem also solved.

but i didn't understand why this is happening.

CAN YOU FIX THIS PROBLEM?

when i see the drivers in my system foder for Vista HP there are two drivers " iastor.sys" and "iastorv.sys" and

and i think the the system is not using driver "iastorv.sys". is there any problem here?

 

Uninstall and reinstall the rapid storage technology driver. You need to restart after uninstalling, and another restart after installing the RST driver.

iaStor.sys is the driver and iaahci.inf is the inf file for the driver.
