flash SecurityError: Error #2028: Local-with-filesystem SWF file

Question

hi my flash app is getting error 2028 when trying to communicate with the internet works fine with flash ide. but when I run swf file with flash player first i get a warning about unsafe operation then I continue and get SecurityError: Error #2028: Local-with-filesystem SWF file file:///C|/Users.... Error

I know how to solve this in local but I need it to work everywhere not just in my local I will not upload my swf to any server I just want it to copy it in a flash drive and work anywhere I want

I put crossdomain.xml same dir with the swf and added these 2 lines:(also imported)

Security.allowDomain("*");
Security.loadPolicyFile("crossdomain.xml");

but nothing changes

my crossdomain.xml:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">    
<cross-domain-policy>  
<allow-access-from domain="*" />    
</cross-domain-policy>

please help

Answer 1

If you're compiling with Flash try to set the Local playback security to Access local files only in the Flash(.swf) Publish Settings:

If you're using the FlexSDK (with or without any IDE), you need to set the -use-network compiler flag to false:

-use-network=false
