Arduino cant open

when ever I click on the application it show the loading page ( small one) then it just closes, What do I do??

please it just worked and then I logged off, got back on and it didn’t work… :stuck_out_tongue_closed_eyes: =( :cold_sweat:

With no details it is going to be very hard to answer your question.

What version of Arduino IDE? What operating system (and version)? What version of Java?

Have you tried re-downloading and running from a different folder?
