Try buring that ISO image again with this Burner.

The original ISO I burned was on this particular drive when Vista originally
was available on the TechNet site; it was written to a DVD+R. I have tried
several diiferent flavors of DVD+R, DVD-R, DVD-RW, etc. As I stated
earlier, the original ISO has worked flawlessly in several diffrent installs
on several different boxes. Sorry, guys, but I can't figure out much else
to do short of purchasing a retail version of the disk (but I'm pretty sure
that will fail also).

DVD-RW disks are often only readable on the drive they are made on or on a
another DVD drive from the same manufacturer as they are made on. I
suggest that you try a non rewritable DVD install image.

The MB's last released BIOS was dated 8/23/06; the one on it is same
version, but released 10 days earlier...don't know if that will make a
difference...may try one on the Tyan website. The board has never been
overclocked, in fact, there is no capability to do it in the BIOS.

Hi,

Check for an updated BIOS for the motherboard, and if you're overclocked
anywhere reset it to defaults.

I tried that several times (with only 2 GB instead of 4); I just tried
dropping down to 1 stick (1GB)...same exact results, i.e., at 28% of
expanding files process, DVD drive light ceases activity, the box sits
still for 8-10 minutes, then install process stops with same message,
..." windows cannot install required files, etc...Error Code
0x8007045d".

There is some hardware glitch with this Tyan MB that prevents either
flavor of Vista (32bit or 64 bit) to be installed.

When I ran Vista Upgrade Advisor from XP, no problems were
detected....and that was with all peripherals attached....I keep
thinking maybe its the ISO but it has worked with several other boxes
without any problems.

Just for the heck of it, try it after removing half of your RAM.

There's a known problem that several people (including yours truly)
encountered when Vista was still in beta: it appears that during the initial
file expansion process the WinPE kernel has only limited error recovery
capability for optical media, and can have problems reading a marginal disk
that can be read without problems on full Windows systems. (The symptom was
also a stop at the same place in the expansion step even with different
disks.)

The workaround was to duplicate the failing disk, but record the
next-generation copy at the slowest speed offered by the mastering software
(and remember to label the slow-burn disks!).

The problem could also be that the drive that burned your working copy, or
the drive in your Tyan, or both are out of spec and are incapable of reading
the sectors on the disk. At some point you might consider swapping the
optical drive in the Tyan box with another drive and see if that fixes the
problem.

Of course, the problem might be something else, but your description sounds
like it's the same one seen earlier.

I have the same problem installing Vista Home Premium,Using an original 32
bit dvd.
on an Acer 9300 laptop.The error code is the same.I had a feeling it has
something to do with the Sata 120GB on NVIDIA MCP51 HDD. Itried installing
Controller and Drivers for the HDD but it kept saying drivers not found.I am
now stuck with no operating system on a laptop 1 year old.any help would be
appreciated.

burn speeds)...checked to make sure DVD drive has latest firmware, removed
memory, changes in BIOS, etc., on and on with the same exact results
(install fails at expanding files-28%). I tried a Vista 32 install with
similar results. I keep thinking this a hardware problem (likely the DVD
drive??), but can't pinpoint it. Any help would be appreciated.
