Sorry I'm not offering any fixes. I'm experiencing the same behavior as well. I'm attempting a clean Vista 64-bit Home Premium install on the following system:

-Asus P5NSLI motherboard w/NVIDIA nForce 570 SLI chipset
-Intel Core 2 Duo 2.13 Ghz
-e-GeForce 7100GS PCI-E video card
-2GB DDR2 RAM
-WD 500GB SATA Drive

It hangs at 14% expanding files everytime. Here is what I have tried:
- updated the BIOS to the most recent version
- removed all cards except the video card.
- tried different Vista disk, dvd drive, and hard drive
- removed 1GB of memory

If anyone has any ideas, I would be very grateful.

Thanks.
