showTrayIcon don't work on windows 7

[Bloopis]

Hi.

I have pulled in my config file the option << "showTrayIcon": true >> but 0 icon appear in my windows tab when I click on close button. Then the application isn't reduced but quitted.

The program is launched by an admin cmd using command line "npm start". A classic cmd change nothing.

System : Windows_NT 6.1.7601

Best regards
