I have recently installed sqldeveloper but i'm getting the below warning window when I try to launch it. This is causing the sqldeveloper to run very very slow and it hangs frequently

I have tried editing the file sqldeveloper.cong as suggested in the window above but does not work
Original
SetJavaHome ../../jdk
Update 1
SetJavaHome C:\Program Files\Java\jdk1.7.0_60\bin\ and all other variations but still getting the above warning window
Update 2 SetJavaHome C:\Program Files (x86)\Java\jre7\bin and all other variations
Please suggest the correct way
C:\Program Files\Java\jdk1.7.0_60? If this so, update conf file, without /bin part and may be try to switch backslashes\to normal slashes/in path. - Nagh
