Blu-ray on a laptop

[Knipples]

My sister has a newish laptop and one of the reasons she bought it was because it had the capability to play blu-ray DVD's.

However she went to play "Watchmen" recently and it said she needed to update the quickplayer so she could play it. There's nothing wrong with the DVD because she played it in my parents blu-ray player.

She did the update with no success, then she rang the helpline she pays warranty for (because its still under warranty) and they told her to update two other things and if that didn't work she would have to do a reinstall of everything on the PC (but that means she has to bung her pics and files somewhere else's obviously - something she could do, but doesn't want to unless its a last resort)

Is there anything else she could download which she could then use to play the blu-ray?
