Failed to install error message with Xcode

I installed Xcode 4.3.1 version today, 

Getting error message "Failed to install" When I try ti install an adhoc application created by new sdk.

Its fixed by selecting the adhoc profile against the 'Release'  code signing identity, Also selected 'Release' on EditScheme - Archieve.
