Windows98 I get 
rb(main):001:0> require 'win32/registry'
=> true
irb(main):002:0> dirs = []
=> []
irb(main):003:0> path = ''
=> ""
irb(main):004:0> Win32::Registry::HKEY_LOCAL_MACHINE.open('SOFTWARE\Vim\Gvim') d
o |reg|
irb(main):005:1*   path = reg['path', Win32::Registry::REG_SZ]
irb(main):006:1> end
=> "C:\\VIM\\VIM63\\gvim.exe"

irb(main):011:0> dirs
=> ["C:\\VIM\\VIM63\\gvim.exe/vimfiles"]
irb(main):012:0>

but in my vim I get
C:\vim 
from echo $VIM

And that's with

irb(main):012:0> puts RUBY_VERSION
1.8.2
=> nil
irb(main):013:0>

or

C:\WINDOWS>ruby --version
ruby 1.8.2 (2004-12-25) [i386-mswin32]

C:\WINDOWS>
