 Bigger Bigger  Smaller Smaller  Reset Reset

Hello!

I can't get arduino IDE to work. Each time I try to start it I get "launch4j" error. IDE does not open, and haven't been working since i've downloaded it. I tried reinstalling java and using patched pde.jar and rxtxserial.dll. Deleting preferences doesn't work either, as I haven't even started IDE yet smiley-sad According to troubleshooting guide I should open run.bat, but I can't find it anywhere (downloaded IDE twice, still nothing). Any help is much appreciated.

What platform?

Assuming some sort of Windows, try launching it from the command line:

arduino --l4j-debug

This will create a launch4j.log file in the same directory. See what that says.

I yield() for co-routines.
