Minecraft launcher won't start

I double clicked on the Minecraft shortcut and the Minecraft icon appears on the taskbar below but the launcher is not coming up. I try clicking on it but that doesn't work. I tried to delete all the files of Minecraft and downloaded again but it doesn't work. I also tried to do the repair thing where you download it while you still have it but no results. Also, the problem might lye in the fact that in the .minecraft folder the only thing there's the launcher data. There's no mods folder or server file or worlds folder or anything.
