Subject: Re: Registry editing in Windows 7

Ok, this is weird. If I use

-----------------

require 'win32/registry'

Win32::Registry::HKEY_CURRENT_USER.open('SOFTWARE\7-Zip') do |reg|
  value = reg['Path']                               # read a value
  puts value
end

--------------------

I get "C:\Program Files\7-Zip\" returned to the console which is 
correct. However, if I try other keys to test, for example:

---------------------

require 'win32/registry'

Win32::Registry::HKEY_CURRENT_USER.open('SOFTWARE\RegisteredApplications') 
do |reg|
  value = reg['Paint']                               # read a value
  puts value
end

---------------------

I get:

"C:/Ruby193/lib/ruby/1.9.1/win32/registry.rb:385:in `open': The system 
cannot find the file specified. (Win32::Registry::Error)"

The permissions appear to be set the same on both keys too.
