Summary

When Eclipse fails to launch with a "no Java virtual machine found" error, often after a fresh installation or a change in JVM location, the underlying problem is its inability to locate the `java.exe` binary. To resolve this, first ensure that Java (either JRE or JDK) is correctly installed on your system. Next, navigate to your Eclipse installation directory and open the `eclipse.ini` file. Within this initialization file, locate and update the JVM location configuration to point to the accurate Java installation path. Saving these changes should then allow Eclipse to launch successfully.

In cases where a new Eclipse is installed or the location of the Java virtual machine binaries has been changed, you may face issue when launching Eclipse. The error would look like.

And if you go to the location specified in the error message, there is no such path indeed. 

And when clicks OK, the program just exits. The issue here is that it tries to find the java.exe binary and launch the program but it failed to locate it and hence exits.

To fix this, you first need to ensure you have Java installed on your system no matter it's a JRE or JDK. Then navigate to the Eclipse installation path and find the eclipse.ini file. 

This is the initialization file loaded when Eclipse launches and there is a configuration of the JVM location.

Update the location to the correct one on the system and save it.

Now try to launch Eclipse again and you will find it can successfully launch.
