Hi CalatiCCC,
The error code may indicate a disruption with the internet connection while downloading the program. We recommend using a wired connection to avoid signal fluctuations. You can try disabling both the firewall and antivirus software installed on your computer to avoid files from being blocked. You may also try to download the program without an internet connection.
For further assistance with your concern, we recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
