iReport-5.6.0 Install successfully but not open.

It is a very common problem that Jespersoft iReport-5.6.0 Designer install successfully but do not open.
It can not open because of JDK version. Now a days latest version of JDK is 1.8 but unfortunately "jespersoft iReport-5.6.0" unable to support 1.8.
In JDK version 1.7 is suitable.
1. download JDK version 1.7  like "jdk-7u76-windows-(32bit/64bit)" and install.
2. Then go to this path in your PC installation "C:\Program Files\Jaspersoft\iReport-5.6.0\etc" and open "ireport.conf" with any test editor.

(Given image may help you to understand)
3. Now add (jdkhome="path of your jdk 1.7") this line
after this (#jdkhome="/path/to/jdk")
4. Finally save it in same place. ( After edit the file may not save in the same place so save it some where else and copy past on the same path with same name)
In Sha Allah the problem will solved.
