I want to install Windows 7 on my laptop. I have Windows Vista right now. When I am reading the instructions it says that all of the hard drive will be erased and that I will need to reinstall programs. Does that mean all the programs I have installed myself will be erased or does that mean my computer will have nothing on it after I install Windows 7?

I got the windows 7 dvd and installed it on my computer. ( I previously had vista home premium) When I was done installing it I checked and I had 32bit OS. I wanted 64. How do I change it? And will it involve wiping my hard drive?
