I used ror on the 32bit windows platform before, such as xp,vista. Now I
buy a new computer and install the windows 2003 64x, and I try to move
the work to the new platform. At the 32bit platform, I just copy the
ruby directory from on computer to another, and set the path, then it
work. Can I do the same thing? Or I must rebuild the ruby on the 64bit
platform? I can’t find any 64bit version at the internet.
