Can't change icon of QT installer

AmrCoder

Hello,
I create a simple installer to my Qt app using Qt installer framework, but i have a problem change the Installer icon i use this config.xml file

<?xml version="1.0" encoding="UTF-8"?>
<Installer>
    <Name>Test my app</Name>
    <Version>0.1.2</Version>
    <Title>Installer Test</Title>
    <Publisher>Me not them</Publisher>
    <!-- Directory name is used in component.xml -->
    <StartMenuDir>I said my app</StartMenuDir>
    <TargetDir>@HomeDir@/TestApp</TargetDir>
	
	<InstallerWindowIcon>logo_o.ico</InstallerWindowIcon>
    <InstallerApplicationIcon>logo_o.ico</InstallerApplicationIcon>
	<Logo>50x50.png</Logo>
	<Background>50x502.png</Background>
	<WizardStyle>Modern</WizardStyle>
	
</Installer>

everything looks fine the logo and so on, but the installer icon not changed at all so what is the mistake i made for that.
Thanks in advance.

Try it with just 'logo_o'

InstallerApplicationIcon: "Filename for a custom installer icon. The actual file is looked up by attaching a '.icns' (OS X), '.ico' (Windows). No functionality on Unix."
