Is it safe to install ActiveScriptRuby on Windows XP with standard Ruby 1.9.2

I use ruby 1.9.2p180 (2011-02-18) [i386-mingw32]. Is it safe to install ActiveScriptRuby (based on 1.8.7)?

Update (after the approval of Luis Lavena):

I have successfully installed ActiveScriptRuby and pik. Proof of:

--------------------- PATH
C:\Ruby192\bin
C:\WINDOWS\system32
...

So now everything looks good. Thanks a lot, Louis!
