Note

ActiveX/Java Uploader Express does not support multiple license keys. See the Upload Suite Editions topic for details.

To register a license key just specify it as a value of the Uploader.LicenseKey property. Here is how you can do that (note that if you have several keys, they should be separated with semicolons):

ASP.NET

<aur:Uploader ID="Uploader1" runat="server" 
	LicenseKey="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXXX;YYYYY-YYYYY-YYYYY-YYYYY-YYYYY-YYYYYY" />

PHP

$uploader = new Uploader("Uploader1");
$uploader->setLicenseKey("XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXXX;YYYYY-YYYYY-YYYYY-YYYYY-YYYYY-YYYYYY");

JavaScript

var u = $au.uploader({
	id: 'Uploader1',
	licenseKey: 'XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXXX;YYYYY-YYYYY-YYYYY-YYYYY-YYYYY-YYYYYY'
})
