I have installed jdk-7u7-windows-x64 on my windows 7 (64 bit) machine, but when I try to install to installer_r20.0.3-windows gives me the following error
Java SE Development Kit not found. Failed to find Java version on “C:\Windows\system32\java.exe”. The system cannot find the file specified
I have set the system variable JAVA_HOME to
%Program Files%\Java\jre7\bin
but it doesn’t help.
Since
installer_r20.0.3-windowsis the installer for the Android SDK;From the System requirements of the Android SDK (here, click System Requirements)
You’ve installed JDK7 which is not listed as working. I’d recommend you install a 32 bit JDK6 since it’s a known working configuration. 64-bit should work, but the installer is known to have had some issues with that version.
