Latest update i can install any app that i don't previously have on the system. If i uninstall photoshop and then try to put cs6 on i get the same message
Error 416 may indicate that the Adobe Application Manager is having problems resolving the address of the server it is trying to download from. Are you using OpenDNS or any type of software firewall or security software?
I would also recommend that you continue with reviewing your installation logs. You can find directions on how to accomplish this at Troubleshoot with install logs | CS5, CS5.5, CS6 - http://helpx.adobe.com/creative-suite/kb/troubleshoot-install-logs-cs5-cs5.html.
The dns gave me an idea so connected the pc to our secondary internet connection and all went fine
Firewall must have blocked access to that one pc on the network as i could install onto another fine. Weird but insanity over thanks
