setup.exe is not a valid win32 application - installed once, 32bit

[philF]

I have successfully installed the Vista Beta on my laptop in a vmware
session. However when I try to open setup.exe from DVD to install on my home
test pc I get the message "setup.exe is not a valid win32 application". This
also happens on my other home (live) PC. I have definitely NOT downloaded
the 64 bit version! I can't boot from DVD either, it moans about the
partitition.
Any ideas what is preventing setup.exe running? The icon doesn't display
properly either. I have never had problems intslling apps before on home
PC;s. I know there are other posts about this but I felt mine was slightly
different as I had already managed to install on one machine and had not
downloaded the wrong dvd.

P.S Loving Vista by the way!!

can anyone help with this? I get the old style setup.exe icon. When I try
to run it I get:

, there are no upgrade paths from Windows XP Professional x64 to Vista x86
or x64. You cannot launch Vista x64 setup in Windows XP x86 or you will get
an "invalid Win32" error. You have to boot off the DVD.

Andre - Did you read my question? I am going from XP x86 to Vista x86. I
have not downloaded the 64bit version. I have already UPGRADED one machine,
I am just stuck on another.

It sounds like a file read problem. If the dvd was used install on another
machine then there is something about the drive in the second machine that
is not correctly reading from the dvd. The error message was related to
cyclical redundancy errors when I got it on one of my installation attempts.
It turned out that there was some misallignment (or something) between the
drives on my machines such that a dvd created on one did not work right on
the other. When I both created and booted from the same drive I did not
have the issue.

I agree, very strange. I have been walking round the office trying the disc
in lots of different machines and I would say that it runs on only 20% of the
machines. It doesn't run on the drive that created it which is even
stranger. Oh well, I am going to 'borrow' one of the drives that works :-)
