Func emulator()
    If _Metro_CheckboxIsChecked($Checkbox1) Then
        
    ElseIf _Metro_CheckboxIsChecked($Checkbox2) Then
        $emulator_link = 'http://d1khghy4erd2oa.cloudfront.net/ndp-32wkjr6zn/Memu-Installer.exe'
    EndIf

    $Download = InetGet($emulator_link,@ScriptDir & "\temp\emulator.exe")
    $File_Size = InetGetInfo($emulator_link,1)
    While Not InetGetInfo($Download,2)
        $Current_Size = InetGetInfo($Download,0)
        _Metro_SetProgress($Progress1,$Current_Size / $File_Size * 100)
