 ariables, look for a value called path. If you find any just open and add a ";" after the line ending in the variable value section.

6. Now enter the path for the java program after the ";" in the value section

e.g. for java 1.6.x = C:\Program Files (x86)\Java\jre6\bin

           java 1.7.x = C:\Program Files (x86)\Java\jre7\bin

           java 1.8.x = C:\Program Files (x86)\Java\jre8\bin
