Huh? JDK not found? (on Windows 7 64-bit)

I am setting up a development environment for the latest Android 2.3 on a fresh install of Windows 7 64-bit.

I first installed the 64-bit JDK 6 (jdk-6u23-windows-x64.exe). Then, I installed 64-bit Eclipse Classic 3.6 (eclipse-SDK-3.6.1-win32-x86_64.zip). Then, I proceed to install the Android SDK Starter Package: installer_r08-windows.exe.

But... upon start it says: "Java SE Development Kit (JDK) not found."

Why? I just installed it.

Is this a mismatch between 32-bit and 64-bit?

How do I solve this?

Update (1): I tried setting the %JAVA_HOME% environment variable, as well as setting the Installed JREs in Eclipse, as suggested below. None of these solved the problem.

It appears that I am not the only experiencing the problem, as this thread suggests: https://stackoverflow.com/questions/1919340/android-sdk-setup-under-windows-7-pro-64-bit

I wonder whether there is a 64-bit version of the Android SDK.

Update (2): I used the zip version instead (android-sdk_r08-windows.zip), ran android.bat, updated all SDK packages, and installed the ADT plugin (8.0.1), not before having to check: 'Contact all update sites during install to find required software'.

We'll see how this goes...

Update (3): It worked! (going to accept @bubu's answer shortly) -- but why doesn't the emulator include the HelloAndroid app when I run it (Ctrl+F11) from Eclipse?

I guess this may be a glitch in the latest version of the Android SDK.

You can try to download the '.zip' version of the Android SDK, run sdk manager.exe and let it update. Then you install the Android development platform (Android Development Tools (ADT) plugin) for Eclipse accordingly and point to the directory in the preferences.

From one of the links:

When there’s a pop up say JDK not found. just press ‘back’ button and then press again ‘next’ button..

This works! The second time it finds it!

According to Android SDK installation doesn't find JDK the installer only knows to look for the 32-bit JDK.
