I have eclipse Mars 4.5.1. I have installed the Enide2015 installed in multiple ways : http://dl.bintray.com/nodeclipse/nodeclipse/1.0.2f/ and using the market place. My node.exe is in a different folder than where the workspace is located. I have specified the PATH user variable to point to that directory and was trying to do that on eclipse using window->preference-> Nodeclipse. However, the Eclipse UI freezes.

My OS is Windows10 - 64 bit. Searched this site, StackOverflow and Eclipse site , could not find anything. Here is the JSTACK dump:
