Neither version will launch it tries to start and then windows reports that Vegas has stopped working "do you want to sent report" and shuts down. Both installs work fine on my workstation (see specs)
I am leaning to the fact that her system is using built in graphics from the asus motherboard, although it is based on a Radeon 4200 I think it may not be strong enough.
YEP just as I thought I just checked the spec page for Vegas and it states a Radeon 57XX or Higher is required, other than that her system will work. Looks like its off to New Egg for a new Video Card..
