Hi, I do not know if this is gonna work for what you want to do, but Strawberry has portable versions which make it possible to have several Perl versions "installed". I have been using this possibility only for a few months (I usually run Perl on Unix, Linux or Cygwin), but I have found portable Strawberry to be quite handy when I need to try things on Windows. You might have to change your Path variable under Windows to prevent problems between different versions. Just my 2 cents worth...
