eclipse won t start - no java virtual machine was found

Question

Eclipse was running fine yesterday  and has been since I installed it about a year ago   Now all the sudden I m getting the following error on startup    A Java Runtime Environment  JRE  or Java Development Kit  JDK  must be available in order to run Eclipse  No Java virtual machine was found after searching the following locations  C  Program Files eclipse jre bin javaw exe javaw exe in your current PATH    I have not changed anyhing Eclipse Java related on my machine but a Windows update was applied to my machine yesterday  so maybe that has something to do with it  but I don t see anything that would affect Java   I ve looked at all the other posts about adding something to your PATH or adding the -vm option to the Eclipse ini  couldn t get this to work  or copying the jre folder to eclipse jre  this worked but doesn t seem like a good long term solution   So I m really trying to figure out how to get things back to the  default  setup without messing stuff up   I m running Windows 7  Eclipse Helios and Java 1 6 0 26

Some time this happens when your Java folder get updated   Open Eclipse folder and search file eclipse ini  Open the eclipse ini file and check whether jre version is same as jre available in your java folder   I faced same problem when my jre got changed from jre1 8 0 101 to jre1 8 0 111   C  Program Files Java jre1 8 0 101 bin to C  Program Files Java jre1 8 0 111 bin

The problem occurred on my machine due to Java version got updated 66 from 60   Pay special attention to it  As said above would like to add   In this file eclipse ini  which is available where you have installed eclipse search for the line below -vm example C  Program Files Java jre1 8 0 66 bin  now try to open this location  in case you are not able to open  that means there is some problem  In my case the version installed was jre1 8 0 60   So there was a small difference which may not noticeable 66 instead of 60   Update it you will be able to open
