  6. Some examples for the installed versions of Java you may have on your computer:

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

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

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

  1. Please note that the above examples are for default Java installation locations and you may have a different path like if you have installed in D:\ or E:\ drive.
  2. Once you put the correct path in the Environment variable, Windows will be able to start the “javaw.exe” program from its correct location.
