You will only be able to run the setup program for the 64 bit version from
Windows XP x64, Server 2003 x64, or by booting from the DVD. The reason you get
the error message is that you are trying to run a 64 bit executable in a 32 bit
environment which isn't possible. As for the disk not being bootable, make sure
that the system is set to boot from cd first. I've seen some systems reset this
for some odd reason. If it is, then you could always try the one-time boot menu,
which most systems have, although each has a different key to get to, and then
specifically tell the system to boot from the drive with the DVD in it.
