Topic: Arduino IDE doesn't start (Read 756 times) previous topic - next topic


recently, i downloaded the arduino IDE and it worked perfectly...
But, a day, I download 1.6.4 version and when I tried to start it, the start icon appeared, it print "loading configuration", "initializeing packages" and... it crashed. I tried 3/4 times again but the same thing at each try. I thank "it's a bug with the 1.6.4" so I uninstalled it and I install again the 1.6.3 (who worked perfectly) and the same thing happened ! my laptop is an old dell with Windows XP. The processor is a 1.6Ghz 500mo of ram Pentium Intel.
Can you help me ?

Sure. Can you please try starting the IDE from the command prompt: use arduino_debug.exe. Before terminating, it will print an error message. Please paste it here

It's all the error message.

It looks like the download json file is corrupted. Please open folder %APPDATA%\Arduino15 and delete all .json files
