Not usually one to raise a query on here but I am stumped on this one.

Adobe Photoshop elements 10 installed on some laptops in the school but they will not update on the school network.

The site sites behind a proxy and the LEA firewall. I have checked with Adobe and they are as helpful as a choclate tea pot. They "do not support" proxy setups so asked about getting external IPs and ports to setup a direct connection but they wouldn't give me anything which is the normal response.

Other Adobe products seem to update over the proxy but for what ever reason, can't get this to work.

The error code is "U41M1C213"

Found this for another adobe product but none of it works either.

It updates fine outside of the network, but thats a little impractical.

Anyone else have this problem and away around it?
