Hi Piotr, On one of my systems, it's almost bare bones. No 3rd party anti-virus or firewall. Just an AIR dev environment for me to test network code against.
I'm not sure what you mean by the cache, but if it's the folder created by the Flex installer here, I've tried closing the app, deleting the whole folder it and trying again many times: C:\Users\[username]\AppData\Roaming\org.apache.flex.installapacheflex Thanks, Bink -- Sent from: http://apache-flex-development.2333347.n4.nabble.com/
