Cannot Install Java Compiler or Java Updates

The thread title states the problem. I have downloaded JDKs several times, most recently a half-hour ago. When I double-click on them, Windows prompts me to confirm that I want to install the software. When I clear the prompt ("OK"), the prompt goes away, but nothing else happens. The same situation exists when I confirm that I would like to accept the most recent Java update.

My machine is an AMD Phenom II Black dual-core
8 GB RAM
17 TB HDD
Windows 7 Professional 64-bit

Why can't I install a Java compiler on my Windows 7 computer?

Java may not be working correctly on your system. The Java (Sun) website offers a lot of help and suggestions to correct possible problems. Here are some links that you might explore to resolve your issue(s):

To find out if Java is working properly on your system visit: Test your Java Virtual Machine (JVM), and then, go to the Java website for the most recent Java downloads.

To check which version of Java you have, go to: Verify Java Version
and Java Help

There are several different Java apps, and you may not have downloaded the correct one for your system (and for your needs). One common problem is that if you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers.

There is also a lot of help offered at this site: Java + You Under the big red /Free Java Download’ button in smaller print is a link to a Java scan called: "Do I have Java?" Let Java scan your machine and see what the results are. If the scan says your machine doesn't have Java installed click the option to install the latest Java version. If the scan says you already have a previous version of Java installed, you can go to Control Panel, Programs and Features, left-click Java to highlight it, and Uninstall it.

Also, the Java app you tried to install may have been corrupted during installation. If you need to remove your current Java app, you can run this tool called JavaRA (from Major Geeks – a very reliable forum) to remove old Java versions.

Here's a link to the Java downloads page: Java Downloads for All Operating Systems

After installing Java, restart your browser and verify Java has been installed correctly. You can verify that it has been installed correctly by clicking this link.
