Just updated from 1.6.0 to 1.6.1 and now the IDE doesn't run. No errors but I can see the Arduino process start up in the task manager and then just quit. 1.6.0 was reinstalled and all is well again. Updated back to 1.6.1 and the problem returns.
Can you use command prompt to run the ide?
open command prompt, type cd "c:\program files (x86)\arduino" (or something like that) then type arduino_debug.exe
It should print the actual error that is keeping the ide from starting. Please copy paste that error here
C:\Program Files (x86)\Arduino>arduino_debug
Error occurred during initialization of VM
java/lang/UnsupportedClassVersionError: java/lang/Object : Unsupported major.min
or version 52.0
Java reports that it's at version 7 Update 21 (1.7.0_21-b11) Trying to do an update results in Java telling me I have the latest version.
Hope this helps
ETA
It works now. I discovered that when I uninstalled 1.6.0 that a number of files were left in the java directory under arduino. Once I deleted those files and reinstalled 1.6.1 it now launches without error.
I tried to install arduino-1.6.4 on windows 7 but No errors but I can see the Arduino process start up in the task manager and then just quit. 1.6.0 was reinstalled and all is well again. Updated back to 1.6.4 and the problem returns.
Same happens with arduino-1.6.2
I opened up the commands prompt (launch cmd.exe from Start button)
I typed cd c:\program files (x86)\arduino then launched arduino_debug.exe
I checked that the error was the VM's reservation space
I opened the two files arduino.l4j.ini and arduino_debug.l4j.ini with Notepad (Run it as Admin!!)
I edited both files changing -Xmx1024M to -Xmx512M
Saved and rerun Arduino IDE, everything fine!
Sorry AmolGulhane07 but I couldn't follow. Does it work? What have you tried doing? Please don't give anything for granted while explaining something on the forum. We can't see your face, we can't see your computer

Hello everyone, just a quick update.
I was in the same situation, Win 7 64-bit 8Gb RAM, Arduino IDE 1.6.1 won't start.

I just installed IDE 1.7.4 and had the same problem that Gord mentioned above on the same platform. I followed his method and it worked for me. Thanks!
Hello ! I am not sure it is the same problem, but still. I am currently using Windows 10 with the new update, and installed Arduino IDE. The problem is that when I execute arduino.exe, nothing happens, and when I use arduino_debug, it can't lauch, and instead displays the "JAVA binary platform has ceased functionning and must close" error.
What can I do ?
