I am trying to install Java EE on my Note book.I have the following problem.
Details are given here.

Windows Vista Home Basic
Service Pack 1
32-bit Operating system

Java version 1.7.0_51
JAVA_HOME=d:\Program_Files\Java\jdk1.7.0_51

Path includes ;D:\Program Files\Java\jdk1.7.0_51

Javac and java runs fine.

I downloaded Java EE file java_ee_sdk-7-jdk7-windows.exe file from
Oracle site on my D:drive. Then I double click on this file. I get a warning
Message "An unidentified program wants to access your computer".I choose
"allow".Then "Launching Java(TM) 2 runtime environment appears for few seconds
And then progam quits without any message.

Have you tried running the application as Administrator?

Have you tried re-downloading the program, it may have been corrupted?

You may also try installing the JDK7 first, changing the java_home environmental variable to the JDK directory instead of the JRE directory, and then installing the SDK separately.
