I have downloaded Eclipse onto my desktop and extracted it from the compressed file using 7-zip. When I try to install Eclipse I keep on getting a window saying that it cannot locate the JDK or JVM on the computer. I have both of these installed on the computer. why can I not install Eclipse? Is there a way that I can install without downloading? I was able to install Eclipse on my 32 bit machines without any problem.

Though you can sometimes get away with not doing it, I advise you to
tell Eclipse exactly where you're getting your JRE (JDK if you expect to
do any Java development).

See http://wiki.eclipse.org/Eclipse.ini .

Double-check whether you're using a 32-bit or 64-bit Eclipse download. The JRE has to match this.

Assuming you remember which Eclipse package you downloaded, which you
probably chose as 64-bit basing it as you might have done on knowing
you're running 64-bit Windows, you should do one of two possible things.

1) Examine the argument to option -vm in eclipse.ini or, if you did not
add this option, determine what JRE your Windows is using by default
when an application launches. (This might not be 64-bit; it depends on
what you've installed.)

2) Better yet, assuming you have a 64-bit Java installed and know where
it is (the path will NOT be C:\Program Files (x86), but C:\Program
Files), tell Eclipse to use it via the -vm option in eclipse.ini.

Please see http://wiki.eclipse.org/Eclipse.ini.

If you plan to develop in Java, you'll want to download the latest JDK
(not merely JRE) from Sun and tell Eclipse where you put it via -vm.

Please note that the argument to option -vm goes on the next line below
it. Please also note that this option goes before option -vmargs.

This should get you running.

It's possible to run 32-bit Eclipse on a 32-bit JRE on a 64-bit machine
(but why would you want to do that?).

Hope this helps.

Haha appreciate the humor; I did download the 64-bit but I will look into the latest JDK not just the JRE. I also do remember the argument option did not have the -vm It only had the -vmargs. Awesome help and hopefully I can get it running. Thank you very much and I shall return if I can not figure it out

If we're still talking about what I answered, then a good start would be
to paste eclipse.ini in here. We can intuit a lot from what we see there.

Looks good except that I'm unable to discern the bittedness of your Java
based on the path you've installed it on. Assuming it's 64-bit to match
your Eclipse installation, what exactly is the error you're getting?

that was the coding downloaded when I installed eclipse. java is saved directly to my desktop so I set up the path to be (openFile
-vm
C:\Users\MRS-16\Desktop\Java\JDK\1.6\bin\javaw.exe)

the error I am getting is when I go to launch eclipse the pop up reads "A java runtime environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\Users\MRS-16\Desktop\Java\JDK\1.6\bin\javaw.exe

Does the path to javaw.exe actually exist? I wonder because Eclipse says
it doesn't. What happens if you open a command window and type?

C:\Users\MRS-16> dir C:\Users\MRS-16\Desktop\Java\JDK\1.6\bin\javaw.exe


Now, it doesn't in fact matter where it's saved to as long as it
actually exists and was successfully installed although for
organizational cleanliness you should relocate it to something like
C:\Users\MRS-16\Java.

I forget how JDK 6 comes for Windows, probably a self-installing archive
or something. You didn't just download the archive and leave it sitting
on your desktop without installing it, right? (And I'm puzzled how you
got it since Oracle stopped supporting and distributing it sometime ago.
You have to try a lot harder to get Java 6 whereas Java 7 is a no-brainer.)

Nitin will probably be back with you before I'm here again and he'll
have wiser things to say.

Best of luck.
