What does mean by Launch4j error?
Hey recently i've bought Arduino Uno board. My drivers and everything get installed easily.. and then i downloaded the Arduino software from their site. It is instructed to extract the file and run arduino.exe from it. i did the same. but when it is opening it shows an error called, Launch4j "An error occurred while opening the application" . It freezes like hell, i can't change my port number for uploading, the tools tab doesnt work, it gets struck. My COM port is 39 for Arduino but in Serial port config in Software it is not visible. Mine is Win7 64-bit(Original), I disabled the Digital signature at boot tart, but still same problem arises. Somebody help me! :(
