This is fine with me. When there are multiple versions installed, there also
needs to be a pointer to the default installation (the one that is on the
path). wxRuby currently uses this to decide where to install itself.

Is there anyone out there (other than wxRuby) that is using the current
registry schema?

How's this look (as an example relative to "HKEY_LOCAL_MACHINE\SOFTWARE"):

  Ruby\RubyCore\default = "182-14"
  Ruby\RubyCore\182-14\InstallPath = "c:\ruby"
  Ruby\RubyCore\182-14\InstallDate = "June 30, 2004"
  Ruby\RubyCore\182-14\Version = "1.8.2"
  Ruby\RubyCore\182-14\Help\Main Ruby Documentation =
"c:\ruby\ProgrammingRuby.chm"
