I am just getting started I down loaded the arduino 1.04 software on to my 64 windows laptop. When I tried to lauch the arduin.exe file, it gave a message saying I need Java Developement Kit 1.5.0 atleast. I tried navigating the Java websit but could not figure out of the many downloads which one I needed. Can someone point me to the correct java kit I need? Which version of the arduino software is best for 64? I did do a search but did not find me answer.
