Like Gary said cooldude101,
There is flash for the default 32 bit browser/s that you use in Windows 7x64. So you'd just have to have Flash installed and it will work with whatever 32 bit (X86) browser you're using. It has nothing to do with if you're using 32 or 64 bit Windows. It has to do with the browsers. 32 bit browsers -Flash =Yes. 64 bit browser -Flash=No.
