Access is denied

[ShaningYu]

I built a application, but errors like that
C:\inetpub\wwwroot\...\xxx.swf (Access is denied).
I copied and pasted the crossdomain.xml into C:\inetpub\wwwroot\, but the errors still exist.
How should I solve this problem?  Thanks.

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>

Run Flash Builder as Admin, the problem was gone.
