I'm trying to install the Android SDK on my Windows 7 x64 System. jdk-6u23-windows-x64.exe is installed, but the Android SDK setup refuses to proceed, because it doesn't find the JDK installation.

I am trying to get Eclipse Galileo to re-run on my computer - i have run it before with no problems but now i keep getting this error: A java Runtime Environment (JRE) or Java Development kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\eclipse\jre\javaw.exe javaw.exe in your current PATH I've just done a fresh install of both the JDK and the SDK I have Windows 7 (x64) what's up with this? / how do i fix it->? UPDATE-> i can't run any of the ipconfig / tracert / ping
