How shall i proceed in order not to break my old gems .. including Rails , etc?

Answer 1

Using the RubyInstaller, can I install Ruby 1.8 and 1.9 at the same time?

A: Yes. By using the RubyInstaller, Ruby 1.8 will be installed by default to C:\Ruby, while 1.9 will be installed to C:\Ruby19. This is by design as Ruby 1.8 and 1.9 offer a different API that may interfere with some RubyGems.

So go ahead and use the default of installing to C:\Ruby19.
