System Error (-1) !!

it means that if the 5th ed device (that's what you are using) is not supporting the target you have selected (Qt 4.7.4), the you should not try using it, instead you should build for the target (Qt 4.7.3) that is actually supported by the device.

@smbianyuccca! How can i build for the target QT 4.7.3 ???

[symbianyucca]

Basically click the Projects icon on right side. Click Symbian devices tab, click the build tab in the symbian device tab. Then click Add button, and select the needed target from the list.

if the required target is not available, then use the updater for the QtCreator, and manually select the required target to be installed with updating.

please use one discussion baord thread for one question, otehrwise you make it impossible to know when your original problem is solved, also I did answer the additional question in your other thread. Basically I have never seen any authentication proxy question while updating, as far as I know, it would be basically same situation as when installing the SDK with online installer.
