Eclipse on 64-bit Windows 7 [message #495526]

Thu, 05 November 2009 04:16

Eclipse User

I recently installed Windows 7 (64-bit) onto my laptop. I am a college student with a major in computer science and I am learning Java. Eclipse IDE for Java Developers worked perfectly fine with my 64-bit Windows Vista, but now, every time I try to open Eclipse, I get this error message:

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\Corbyn\Desktop\eclipse\jre\bin\javaw.exe
javaw.exe in your current PATH

I'm not completely sure what it's asking for, so help would be greatly appreciated

EDIT: Forgot to mention that there is no such folder ( \jre ) in my eclipse directory.

I can't specifically answer your question, but as noted frequently in
this forum, you should specifically use the -vm switch in your
eclipse.ini file to avoid such trouble.

It's telling you it can't find the JRE that eclipse needs to run. Have
you installed one?

I am having the same problem as the original poster, I tried doing the fixes posed in the link (I.E. adding those commands to the .ini file), but when i do that, it seems like clicking the eclipse.exe does nothing. Any suggestions/ideas?

Try to see if your path variable is set... go to My Computer properties > Advanced system settings > under Advanced tab you have the Environment variables button, click it, and under System variables you should have the path variable. That variable is a list of paths that allow you to access exe's from anywhere just by typing their name and those paths are separated by semi-colon (;)... in there you should have something like ;C:\Program Files (x86)\Java\jre6\bin

If you don't have it, you either need to install JRE... and as a side note, you'll only need the 32-bit one, no need for 64-bit one at all... but if you do have it installed, just look up the path of java.exe and add it to that string... also don't end it with a ; or a \ and don't put the path in quotes.

I would recommend AGAINST adding Java to the system path, especially if
you want to maintain multiple versions of Java on your system. Using
eclipse.ini (instructions posted above via wiki link) is the best way to
specify what JVM you want Eclipse to run in.

It could be a problem with how you formatted eclipse.ini - as the wiki page says, the format is very particular. Double-check what you've done and even post it here for us to review, if you want.

You did what? Be specific, and refer to already-supplied advice.

I'm having the same problem. Edited the system environment variables AND the eclipse.ini. Now I get the error on the attached image.

Here is my eclipse.ini:

-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1. 1.R36x_v20100810

Your message is devoid of all context and must refer to an earlier
thread from which it is disassociated.

I can tell you right now, however, that you're telling the Eclipse that
uses this .ini file to use a 32-bit JRE. That's a no-no if your Eclipse
is in fact a 64-bit one, which it appears to be.

how to solve this error

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\Corbyn\Desktop\eclipse\jre\bin\javaw.exe
javaw.exe in your current PATH

This error happens when a JVM 32-bit (JRE/JDK) is tried to be used with an Eclipse 64-bit or otherwise.
