I tried downloading sdk using install manager (64 bit) in windows 7. 

when i executed the install manger, “cannot execute java even if it was installed.. check environment variable or java versiion(over 1.6)please”

error appears. i dont think there is any problem with env setup.

When i execute java -version and javac -version, it shows proper versions.

>java -version

  java version “1.8.0_05”

> javac -version

 javac 1.0.0_05.

Please recommand the proper steps to download SDK and IDE.
