I installed Energia onto my computer (in fact, on two different ones, just to be sure of myself, and got exactly the same problem on each one). Its runs FINE the first time (with an MSP432). But since it is inconvenient to open it from its unzipped folder, I created a shortcut and moved it onto the desktop (of Windows 10). Then, I clicked on that shortcut and, while the flash screen of Energia appear, ... in a flash ... it disappears in less than a second and ... nothing. Doh, not so bad, that what I thought, since I could run it again from its original place, ... that was I thought... but I was WRONG. I cannot run it from that place either, clicking on the exe or as administrator. Same flashing flash screen and next, nothing. Maybe a short flash of a command window (which shows itself only for a flash), but nothing. I suspect that trying to run it with the shortcut "destroyed" some useful initialisation. So I tried to re-unzip again the folder, but no, still the flashing flash screen and then, nothing.
I did it on two computers, exactly the same problem on both.
If I run energia_debug from the command window, I get an error: Incorrect IDE installation folder: Your copy of the IDE is installed in a subfolder of your sketchbook. Please move the IDE to another folder.
I did, no joy.
