Vista - **Windows 7 won't install on VPC

dell Inspiron 530, quad 2.6ghz, 3gb, XP SP3 32bit, VPC 2007 sp1 XP guest,
networked
-------------------------------------------------------------------------------------

When I try to install Windows 7 demo, I get the error message:

Error 0X80070570 Windows cannot install required files.
The filemay be corrupt or missing.
Make sure all files required for installation are available and restart the
installation.

I connected to the ISO and ran the install. It stalls in phase 2 after it
says it has copied all the files, half-way thru decompression stage. I have
run the installation several times.

I have downloaded the distrib twice and have gotten the same results with
both copies.

VPC2007sp1 is running on the machine correctly. I stopped the VMachine
from running during the install.

Any idea what I am doing wrong?

Thanks,

I've only seen this from a corrupt ISO, but make sure you have enough
space free on the partition that houses your VHD file.

I had the same problem when I tried to install Windows 7 by accessing the ISO
image directly.
There is a very simple solution: mount the ISO on a virtual drive.
A number of free Virtual Drives apps can be found on the Internet.

I may have found part of the problem.

It appears that the files are being accessed one block at a time, in either
ISO or physical DVD mode

What on earth could be causing this?

Experimenting, I upped the priority of VPC from normal to high normal and
then to high.

In high, I got decomp to rather quickly go as far 34% before getting the
same error message. The VHD is 64GB, so I don't understand what is causing
the files to be missing at any given time in the decompression.

This confuses me, as VPC should have one core all to itself, so I can't
understand how it could be so priority sensitive with a lightly loaded
machine.

ZAlarm and PCDoctor show no infections, so I don't know what could be
causing this situation.

Any thoughts or suggestions? It may certainly be something peculiar to my
machine, so any ideas on what it might be?
