Java EE 6 SDK uninstall 'Could not find the required version of the Java(TM) 2 Runtime Environment'

Question

I want to uninstall my Java EE 6 SDK on my windows 7 machine, but when I run the included uninstall program, I get the following error.

Error: Could not find the required version of the Java(TM) 2 Runtime Environment in'(null)'. 

Followed by...

This application needs version 1.6 or higher of the Java(TM) 2 Runtime Environment

How to fix this? Do i have to install the java 2 runtime environment just to uninstall my Java EE 6 SDK?

Answer 1

Make sure you have both the 32 and 64 bits version of JRE installed. The Java EE x64 installer won't work without the 32 bits JRE installation.

Answer 2

I got the same problem. By installing the program with following parameters it worked like charm.

java_ee_sdk-6u4-jdk7-windows-x64.exe -j "D:\Program Files\Java\jdk1.7.0_06"

where D:\Program Files\Java\jdk1.7.0_06 is the folder I have installed JDK 7 in my system.

That's right. You need to install Java SE from http://www.java.com in order to be able to run the Java EE (un)installer. It's written in Java, so it needs at least a JVM.
