Win 7, using Eclipse Installer to try to install Eclipse. Getting the message, "Unfortunately the Java version needed to run Eclipse Installer couldn't be found on your system. ..."

At the command prompt, ran java -version and says Java 1.8.0_45 is installed.

index.php/fa/34765/0/

Please help. Thank you.

Is that a 32-bit version of 1.8.0_45? If it's installed under "Program Files (x86)", it is, and you'll need to install a 64-bit version.

Looking at this information:

https://stackoverflow.com/questions/2062020/how-can-i-tell-if-im-running-in-64-bit-jvm-or-32-bit-jvm-from-within-a-program

It has this description:
Just type java -version in your console.

If a 64 bit version is running, you'll get a message like:

java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)

A 32 bit version will show something similar to:

java version "1.6.0_41"
Java(TM) SE Runtime Environment (build 1.6.0_41-b02)
Java HotSpot(TM) Client VM (build 20.14-b01, mixed mode, sharing)

Note Client instead of 64-Bit Server in the third line. The Client/Server part is irrelevant, it's the absence of the 64-Bit that matters.


So this suggests to me that you have a 32 bit Java installed and you are using the 64 bit installer which needs a 64 bit version of Java.

Go here:

https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

And be sure to choose " Windows x64 207.46 MB jdk-8u201-windows-x64.exe"
