I have just installed QT and signed the HelloWorldQT app with my dev cert and it works fine on E63.
However the QFaceBook example "GetFriends" (http://gitorious.org/qfacebookconnect/pages/Home) gives "unable to execute app for security reason(-46)" error message.
I have changed the capabilities for getfriends.exe, qfacebook.dll and qjson.dll to
"NetworkServices ReadUserData WriteUserData ReadDeviceData WriteDeviceData SwEvent Location LocalServices UserEnvironment"
but still no use.
I was somehow not able run the app on simbian emulator so have blindly taken the above capabilities.
Has someone had success running getfiends or any other QTConnect example on device? If yes can you please give me the capabilities used?
