Viewer 2 only workds sometimes on a friends computer

[jamie Cheeky]

Hi all my friend is trying so hard to get viewer 2 to work it only works sometimes in her words 1 in 5 times - but most of the time she just gets a blue screen after log in. I suspect it might be her memory??? - she is very very un-computer friendly - and this will probably mean her leaving sl if we cant figure this out with a very easy option...I will post her computer information that she gave me - if anyone has any ideas please reply....thanks in advance

what's the exact OS because if it's XP there are some viewers that requireservice pack 3 to run check to make sure the AMD processor features SSE2 a search will bring up some sites that give you this info i have a feeling the official LL V2 requires SSE2, for the blue screening first try updating the drivers for the graphics card  often after going BSOD the system will tell you what caused it and what you should do to prevent it when you log on to the computer
