Impossible to lounch Appium Desktop App v1.4.1 on Windows 7

OS: Windows 7 x64
Appium v1.4.1 from source


I install Appium Desktop App to Windows 7 by running “appium-desktop-Setup-1.4.1-ia32.exe”
But after running - no any dialog window is displayed, appium is installing without any questions (installiation folder for example).
Installiation is successfull, Appium window appears automatically, but I can’t find directory where Appium.exe is installed.
No any desktop shortcut is displayed and search can’t find Appium.exe. So every time for starting Appium server I have to install Appium.

See the screenshots:
