Java couldn't be found.... [message #1801876]

I am trying to install eclipse, but I keep getting the following message:

Quote:

Unfortunately the Java version needed to run Eclipse Installer couldn't be found on your system. You need the following version or a higher version:

I am sure that I have the 64-bit version of the jre installed, as it is in the Program Files folder.

I also have the path set correctly. Powershell returns the following when I enter "java -version":

(actually I'm not allowed to include links as a new user)

I'm at a loss as to what to do from here. Further searches only reveal the above two as the most common problems.

Why would you need a link to show us the command line output?

And could you post the complete exact path of where Java is installed on your machine. You should not need to set any system paths; the installer looks in the system registry...

Not OP but I have the exact same issue.

I did not have JAVA before, but I installed JDK 11.02 according to the URL provided, with all default installation options. I have restarted the system.

C:\Program Files\Java\jdk-11.0.2

I have verified that JAVA is properly installed with both the JAVA control panel and with CMD java -version

java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) Client VM (build 25.171-b11, mixed mode)

The installer looks in the system registry, so if you only unzipped the Java 11 SDK but didn't install it,the installer won't find it. :-(

The Java 8 you do have installed is a 32 bit version, and that doesn't work. The installer also checks the system path, but as you notice, that points at Java 8 and is 32 bit. So you need to manually change the system path...

Saw this and while the above folks are right, somehow my default installation was 32-bit.

Go to console and write: "java -d64"

If the output says: "Error: This java instance does not support a 64-bit JVM." that means you need to uninstall java and then reinstall (just use the eclipse options).

To uninstall (Windows 10), go to Apps & Features, Search 'Java' and just hit uninstall.

Get the right version and you should be good to go :)
