Unable to install .ipa file on real device

Hi, I’m newbie on iOS automation testing, I want to install an .ipa file on my iPad, but from Xcode I got, “App installation failed, Avalid provisioning profile for this executable was not found”, from iTunes, “installing” message is displayed and the app never is installed.

I dont have the source code, so I am unable to build it myself.

Any ideas, suggestions?

Thanks in advance.
