Try reburning the ISO at a low speed, 2x recommended, also do a CRC check on
the ISO to find out its integrity. Nero MD5 Verifier is a recommended
choice. If setup still fails, its likely a bad download.
I use the one from Ahead Nero
http://ww2.nero.com/nero6/eng/Nero_MD5_Verifier.html
Here are the MD5/CRC values for x86 or x64 depending on which every ISO you
downloaded:
x86
- File Size = 3.12 GB (3,355,598,848 bytes)
- CRC Value = 0x67E089E0
- MD5 Value = 0E733AB1A8E8FF9A8684FD3639332773
x64
- File Size = 4.01 GB (4,309,368,832 bytes)
- CRC Value = 0x48697711
- MD5 Value = E43502D0A15EADD551119D5639859E04
Paste the MD5 Checksum for either x64 or x86 depending on which one you want
check in Step 1, Step 2 - Browse to where you stored the ISO on your drive
and open it and it will automatically start the varification process and
generate the has in the third field, if it matches Step 1, then you are
safe.
If none of this works, I would try installing on a clean partition.
A lot of persons are contemplating about upgrading their one and only,
production
install of XP. If you are itching to do that, DON'T! DO NOT upgrade your
existing install of XP if you use it for work or you use it on a daily
basis. Not because Vista is at BETA 2 means its ready for prime time or
production environments, it is for testing and to get feedback on what's
wrong with the product.
I also suspect some persons think Vista has been finalized, no its not, its
still in development. I know Vista looks enticing and all, but it is still
not ready for prime time and the numerous reports of unsuccessful,
problematic clean installs, upgrades are proof of that.
If you want to try upgrade scenarios at least make sure you do it on a spare
installation of XP, you have a back up image of your existing install or
simply do a clean install on a separate drive or logical partition. For
those who have already upgraded their installations of XP and want to return
to XP, your only option is to format that drive and reinstall it. There is
no way to uninstall Vista.
Also, 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.
