The reason why there is no GUI could be due to OS setting.
If you goto "%userprofile%" folder, see if you have ".accessibility.properties" file.
This file can be created by following steps.
1. Go to: Start->Control Panel->Ease of Access->Ease of Access Center
2. Select “Use the computer without display”
3. In the section “Other Programs Installed” select/check the checkbox “Enable Java Access Bridge”
Or, you might have run the following command.
jabswitch.exe is located in your "JRE/bin" folder.
If you had this setting enabled, it forces javaw.exe run by the installer to not display the GUI window.
Reversing these steps would not fix your problem.
You must delete this file "%userprofile%\.accessibility.properties".
Only then the installer will display GUI.
