Loading XML from exe file query

Hi, I have a Flash movie exported as an exe file, that loads information from an XML file situated on a server, like so:

var urlLoader:URLLoader = new URLLoader();
var urlReq:URLRequest = new URLRequest(“http://server.mydomain.co.uk/info.xml”);
urlLoader.addEventListener(Event.COMPLETE, loadXML);
urlLoader.load(urlReq);

I’m testing the exe from my desktop and it’s working fine, calling the URLs in my default browser. I would like to ask, will the exe work from any machine with internet access? Or are there likely to be problematic security issues? I haven’t had to change any security settings for the exe to work on my PC.

I’m sure the answer to this issue is already on the forum somewhere, but I just want to make sure that there are not likely to be any problems in my particular situation (zero margin for error with these clients!).

Thanks in advance to anyone who can help
