This is not specifically a PHP issue, but people who use computers can run into this problem and might be able to provide me an answer.
I am trying to go from 32 bit Vista to 64 bit Windows 7.
The 32 bit Vista was installed by mistake. My system can handle a 64 bit OS. Now I have finally found the time to upgrade. But the 64 bit intallation DVD can't be read from my OS. Any Advice?
Do I need to boot from that DVD drive? Will that work?

Have you tried it? How would you install it if no OS had been installed already?
You can't upgrade 32 bit to 64 bit... And for example, you can't upgrade Vista Home Premium to Win 7 Pro even if they are the same 32/64 bit.
