I realize this question has been asked before, but it's been years since the last one with any good answers.

I've downloaded eclipse, extracted the files and tried to open it, but it comes up with this 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\Riversong\Downloads\eclipse-standard-luna-R-win32-x86_64\eclipse\jre \bin\javaw.exe javaw.exe in your current PATH"

What do I need to download or change to make this work? I have Windows 7 and the latest Eclipse. (On the Eclipse folder, I do not have eclipse.ini as file. It is called eclipse instead but is still opened as a notepad file.)

Thank you!

    It's not recommended to do most of the things mentioned in that question's answer, including changing your system PATH environment variable. Using eclipse.ini is the recommended approach. See my answer below. Commented Aug 12, 2014 at 16:24
  • This is not really a duplicate; I'm pretty sure the problem here is due to Windows hiding the extension for the eclipse.ini file (see my answer). Commented Aug 12, 2014 at 20:03

Windows, by default, hides the extensions for many types of files. If you have a file that appears to be named eclipse but opens as a text file and has contents like those seen at https://wiki.eclipse.org/Eclipse.ini then you've got the right file v(you can verify this by looking at the file's properties). Use the instructions on that page to add the -vm parameter so Eclipse knows where to find the JVM you want it to run in.

By the way, if you want to turn off this annoying feature of Windows, in File Explorer select the Tools menu, then Folder options..., then go to the View tab. There you can find a checkbox option labeled Hide extensions for known file types.
