I am in desperate need of help. I have been stuck on this problem for days now and have been looking all over the internet, you are me last hope.
I’ve been trying to create a Windows Installer using WIX and all seems well until I try to customize the standard UI’s (minimal to be specific).
I am trying to apply custom images on the installer wizard I kept my bmp files in the installer folder along with remaining files I want to pack. But the custom messages and images not applying to installer. Blow is my code snippets,

    <Package InstallerVersion="500" Compressed="yes" InstallScope="perMachine" />
        <Media Id="1" Cabinet="media1.cab" EmbedCab="yes" />

        <Property Id="WIXUI_INSTALLDIR" Value="INSTALLFOLDER" />
        <Property Id="WixUIBannerBmp" Value="E:WixToolsetCRMWixProjectCRMSetupImagesbanner.bmp" />
        <Property Id="WixUIDialogBmp" Value="E:WixToolsetCRMWixProjectCRMSetupImagesdialog.bmp" />
        <Property Id="CustomWelcomeMessage" Value="Welcome to the CRM Setup Wizard. This wizard will guide you through the installation of MIMICS CRM. Click Next to continue." />
