</Wix>

I get this error and warnings:

The extension of Icon 'ikonka' for Shortcut 'DesktopShortcut' is not "exe" or "ico". The Icon will not be displayed correctly.*

Why? I give ICO file.

The extension of Icon 'ikonka' for Shortcut 'DesktopShortcut' does not match the extension of the Key File for component 'ProductComponent'.

Have you any idea?

You appear to be missing an Icon element.. e.g.

    <Icon Id="City.ico" SourceFile="City.ico" />
    <Component ...>
        <File ...>
            <Shortcut Advertise="yes"
                Id="DesktopShortcut"
                Directory="DesktopFolder"
                Name="AdministKOB"
                WorkingDirectory="INSTALLDIR"
                Description="Elektroniczna książka budynku"
                Icon ="City.ico" />
        </File>
    </Component>

You must have an extension on your Icon id of ".exe" or ".ico".

Icon Id="ikonka*.ico*" SourceFile="Files\AdministKOB.exe"/

It is easy:

<Shortcut Directory="DesktopFolder" Id="DesktopShortcut" Name="YourApp" Description="DescriptionOfYourApp" Target="http://localhost/" Icon="YourAppIcon">
      <Icon Id="YourAppIcon" SourceFile="$(var.BinDir)\favicon.ico" />
</Shortcut>

I put tag on the top of my listing :) I use icon from exe file. Wix requires the same extension for file icon file and my file (shortcut on desktop)

Thanks for you attension :)

In addition, the shortcut's icon property can take a direct path to an exe or ico file, however, there cannot be any spaces in the filename or it will error:

The Shortcut/@Icon attribute's value, '"C:\Users\yadayadayada\Data Migration.exe', is not a 
legal identifier.  Identifiers may contain ASCII characters A-Z, a-z, digits, underscores 
(_), or periods (.).  Every identifier must begin with either a letter or an underscore.    
SetupProject    C:\Users\yadayadayada\SetupProject\Product.wxs  53

Following worked for me. Milage may vary.
