version 1.7 of the jvm is not suitable for this product. version 1.8 greater is required for eclipse nano in window

Simply download 1.8 JDK from Java SE Development Kit 8 Downloads install it, then copy the jre folder & paste it in:

"C:\Program Files (x86)\EclipseNeon\"

Then rename the folder to "jre", start the eclipse again it should work.

sudo /usr/sbin/update-alternatives --config java

and select the jvm 1.8

I faced the same issue (Windows 10). You need to set the "JAVA_HOME" system environment variable to point to JDK 8 folder and edit the "Path" system environment variable to have a new path to JRE 8's bin folder, this should be at the top of the list.
