Arduino IDE 1.6.1 not launching on Win7/64

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.

Has suggested:

  • 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!
