Can't run WebStorm 11 on Mac OSX El Capitan

When I doubleclick WebStorm.app in Finder, just some icon become visible for a milliseconds in Dock and immideately disappears without any errors.
I already checked https://intellij-support.jetbrains.com/hc/en-us/articles/206827627-IDE-doesn-t-start-after-updating-to-Mac-OS-Yosemite-or-Mavericks and installed Apple JDK 1.6 without any changes.
Same behaviour was with WebStorm 11 EAP version.
Will appreciate any advices how to run WebStorm.
