reinstall the operating system, as far as i am aware there is no other way.
Switching from 32 bit to 64 bit or vice-versa requires a clean install. There is no way to directly migrate from one to the other.
you have to do a clean reinstall as the two version are designed fundamentally different. You would need a win 7 64bit install disc.
