Hello
After some days with a problem on the arduino scketch editor.
The famous error "an error ocurred while starting the application" launch4j
So today I saw that the folder Arduino on documents was an infinite folders libraries like this:
C:\Users\X\Documents\Arduino\libraries\libraries\libraries\libraries\libraries\libraries\libraries\libraries\libraries\libraries\libraries\libraries\libraries............................................................
I renamed that folder as "C:\Users\X\Documents\XArduino" and arduino created a new one, in this moment the arduino scketch start working fine...........
