[69s fine 68s great]

my ruu will not work on my vista os... but when i go to my buddys computer which is xp, it works just fine. i get to the last step on the ruu and then it will show a file missing screen.. i have already deleted and reloaded build dos and the updates as well. i am syncing with microsoft syncing program.. do i need something else to sync with.. and i do have oipro 2.4o. my main concern is why can i flash using xp but not vista
