Unable to install Android for Windows 7 because JDK is not found

Question

I have JDK SE7u4 installed in windows 7. I tried to install Android on Windows 7 using the installer_r18-windows.exe but no avail.

The setup window showed the message saying that the Java SE JDK not found and

ERROR: Failed to find Java version for C:\Windows\System32\java.exe
The system cannot found the file specified.

If you believe you have a JDK installed and it was not properly recognized, simply set an environment variable JAVA_HOME to point to it

I right clicked on Computer > Properties > Advanced System Settings > Environment variables. I created a NEW system variable called JAVA_HOME and set the value as C:\Program Files\Java\jdk1.7.0_04\bin or C:\Windows\System32\java.exe.

I ran the installer again — the same error message still appeared.

Solution 1

You might have a different problem, but here is the solution I found to the same error message:

1. Go to C:\Windows\system32
2. Rename java.exe to something else, for example java2.exe
3. Run Android SDK Setup again

Solution 2

I downloaded Eclipse Juno and I wanted to install Android SDK too. It only worked by installing the Java JDK 'Windows x86 79.48 MB jdk-7-windows-i586.exe' from oracle.com (despite the fact that I use Windows 64-bit).

Remember to uninstall every Java JDK kit from control panel first before you install the JDK above.

Solution 3

As the OP commented on this answer:

I installed Java JDK 7u4 for windows 7 64-bit. I think the Android SDK installer was trying to detect the 32-bit version of the JDK, so I went to install the 32-bit version of the JDK.

Then I ran the Android SDK installer again. This time the installer detected the JDK and it installs the SDK. That was my solution.

Solution 4

Browse To C:/Windows/system32 and find a file named "java.exe". Then, just rename it to "java2.exe". Voila ! It will work.

Which version of JDK you are using?

I installed Java JDK 7u4 for windows 7 64-bit. I think the Android SDK installer was trying to detect the 32-bit version of the JDK so i went to install the 32-bit version of the jdk. Then I ran the Andoid SDK installer again. This time the installer detected the JDK and it installs the SDK. That was my solution.

This answer makes no sense. All you did was install the current version of the Java SDK.

@Ramhound, makes. he states that he installed x86 version even on 64b windows.

Probably not needed as an answer since there are many other good answers and the question is over 4 years old.
