New Machine Vista Install woes

Ok, this is my third machine in the last year that I have built fro
scratch, the first 2 being 32 bit Vista machines, and went off without
hitch. So now I go to build my new Vista 64 bit machine, and am runnin
into an install problem. I can boot from the disc from the DVD drive
and even enter the product key, but once it goes to the next step o
installing, I get the following error

"Windows cannot open the required file D:\sources\Install.wim. Mak
sur
all files required for installation are available and restart th
installation. Error code 0x8007000D.

Here is my machine

AMD Phenom 9850 BLACK EDITION 2.5GHz 4 x 512KB L2 Cache 2MB L3 Cach
Socket AM2+ 125W Quad-Core Processo

ASUS M3N72-D AM2+/AM2 NVIDIA nForce 750a SLI ATX AMD Motherboar

OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500
Dual Channel Kit Desktop Memor

MSI 8800GTS (G3) 512 Video Car

The version of Vista I have is a OEM version so Microsoft will no
offer any support. Im just an amateur builder and have built all thre
for family use, but this third machine is killing, especially since it
MY machine..

HELP!!!!!
