As rvilkman says, you will have to re-install. There is no quick switch you can perform, microsoft doesn't do it. Just back up your stuff then re-install it.
 
You need to do a clean reinstall.

If you can borrow a 64 bit windows 7 dvd, you can use it to install the 64 bit version, and still use your current product code to activate.
Microsoft used to send you a 64 bit version of vista for a handling charge of $10 if you wanted to upgrade from a 32 bit version. Don't know if that is available for windows 7.
