I downloaded the Java 7 software from get Java at http://java.com/en/download/index.jsp and Java FX was NOT downloaded.

Hi Calls,

I've been doing a bit of searching and it seems that you can safely uninstall JavaFX 2.1.0. Here are a couple of links which you may find helpful:

Uninstalling JavaFX

Vista - Java FX 2.1.0

What you need to do is to go to 'Add or Remove Programs'/'Programs and Features' (depending on your OS) and uninstall JavaFX 2.1.0 just as you would with anything else; this shouldn't affect your JRE in anyway. I've got rid of it on our XP desktop and both of our Windows 7 laptops and no problems have arisen becaue of this. In the very unlikely event that you do experience any difficulties, you can always reinstall it.

Why wasn't JavaFX installed on my machine?  I got Java 7 Update 4 from the java consumer website.  Perhaps you installed the Java Development Kit?  Next time, install Java from the Java consumer website at www.java.com.

Windows 7 Home Premium (64 bit)

Edit: Just found the answer.  Wanted to point out the FAQ says:

However, starting with JavaFX 2.0.2 and Java SE 7 Update 2 (December 2011), Oracle has started rolling out a solution through which the installation of the JavaFX Runtime when the Java SE 7 Oracle JRE is installed. Additionally, the JavaFX SDK is now part of the Java SE SDK (JDK). When Java SE 8 reaches General Availability (GA), the JavaFX Runtime will become part of the Oracle JRE.

This mean the java downloaded from the Oracle website.  Oracle webite java is aimed at devs anyways.  Java 7 has been out on the Oracle website before it was repeatedly tested and "finalize" to be released on the Java consumer website.

What is the difference between the JRE and the Java SE platform?

	JRE (Java Runtime Environment)	Java SE (Java Platform, Standard Edition)
Who needs it?	Computer users who run applets and applications written using Java technology	Software developers who write applets and applications using Java technology
What is it?	An environment required to run applets and applications written using the Java programming language	A software development kit used to write applets and applications using the Java programming language
How do you get it?	Distributed freely and is available from: java.com	Distributed freely and is available from: oracle.com/javase

What is the difference between the JRE and the JDK ?

JRE (Java Runtime environment)	JDK (Java Development Kit)
It is an implementation of the Java Virtual Machine* which actually executes Java programs.	It is a bundle of software that you can use to develop Java based applications.
Java Runtime Environment is a plug-in needed for running java programs.	Java Development Kit is needed for developing java applications.
The JRE is smaller than the JDK so it needs less Disk space.	The JDK needs more Disk space as it contains the JRE along with various development tools.
The JRE can be downloaded/supported freely from java.com	The JDK can be downloaded/supported freely from oracle.com/technetwork/java/javase/downloads/
It includes the JVM , Core libraries and other additional components to run applications and applets written in Java.	It includes the  JRE, set of API classes, Java compiler, Webstart and additional files needed to write Java applets and applications.

Hi sammys123

It happens to me as mentioned by "Calls" without asking any questions whether I want ot install or not. even though I use the download you mention. I have tested in multiple machines and it's the same thing. Now Oracle should explain properly if this Java FX is required or not for installation of Java 7 Update 4. Can it be uninstalled. And if Uninstalled will Java 7 Update 4 will work properly as it should.

Strange.  I used Windows Offline (32-bit)  on my machine twice and didn't get the Java FX. .  I don't have Java FX installed at all.  Did you get it from the "Java" website (consumer) or the Oracle website?  I only updated after Java 7 Update 4 was released on the Java website.  Never installed from the Oracle website.  What OS are you using? Vista like Calls?

I downloaded it from the get Java link when you go to java.com.

But want to thank Madeline for finding all that info and for advising that JavaFX is not really necessary. Kinda what I thought, as similar to when you update iTunes and get Bonjour as part of the download (without option to decline)
I wonder if JavaFX was walways part of the Java Updates, but just not shown as a seperate program?

Hi All,

A few points!

1. @ MehulBhai,

Yes, JavaFX can be uninstalled - see my previous post #12.
 
2. I have uninstalled JavaFX 2.1.0 from all 3 of my computers without any difficulty - details in my signature.

3. Java 7 Update 4 appears to be working fine without JavaFX. Many people don't have Java at all on their PCs and manage very well without it.

4. I have definitely NOT installed JDK 'by mistake' - Java on all 3 PCs show 'Java Runtime Environment' under 'Settings'.

5. Until this recent update, it has been possible to get Java 7 from Oracle only; this is the first time that the Java site has offered it for download.

6. I've noticed JavaFX before on my PCs - probably because I got Java 7 from Oracle and it's quite possible that Java don't include JavaFX in their download.

Thanks Calls, it was kind of you to say what you did, I appreciate it!

Not sure about what sammys123 is meaning about the oracle website.
I got my Java 7 update4 by going to
java .com
Clicked on the free java download button
then clicked agree and start free download
all of the urls showed as java .com and the actual download &ava setup 7)came from sun, com url.
Now I''m in the states if that makes any difference

Hi Calls,

sammys 123 means that you can download Java from either the Java website as you did, or from the Oracle site. Until recently, you could download Java 7 only from the Oracle site, but it's available from both sites now as you can see from the following links:

Java site

Oracle site

It doesn't make any difference where you are; I'm in Wales and it's the same for me. By the way, you may have to allow cookies on the Oracle site to be able to view it properly.

Java 7 is now at update 5 with FX at 2.1.1 I guess if you have it you may want to update and I find java.com and Oracle to be the same..........Best......Gorpy1
