I try to open eclipse-inst-win64.exe to install eclipse 2019. But I get this error report:
index.php/fa/36554/0/

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 have search in forum, two main reason for this are JAVA_HOME/PATH not configured correctly and JVM is 32bit while OS is 64bit. But I check my system environment variable and JVM, Both of them are correct. And my JVM version is jdk1.8.0_172.

Does anyone know how to make eclipse recognise my JDK ?

Is javaw.exe also on your path? The installer looks in many places, including the system registry, the JAVA_HOME variable, and on all the folders on the PATH. It probes each using javaw.exe however, which is why I ask.

You can also run the installer from the command line and specify explicitly which JVM to use, e.g.,

.\eclipse-inst.exe -vm "C:\Program Files\Java\jdk1.8.0_121\bin"

Sorry to reply you so late. I check my path, javaw.exe is on the same directory with java.exe .

This picture shows my %JAVA_HOME%/bin, java,javaw are all here and they are 64bit.

And I use code like .\eclipse-inst-win64.exe -vm "xxx" and get the error message like this:
index.php/fa/36597/0/

So, I choose to use the full package instead of eclipse-inst. I download the full package "2019-09/R/eclipse-jee-2019-09-R-win32-x86_64.zip" , unzip it and then double click to start it. It works well.
