i followed these instructions for building an adhoc version in xcode 4.0 (4.3 compilier)
same project worked for adhoc before i upgraded to 4.3
http://diaryofacodemonkey.ruprect.com/2011/03/18/ad-hoc-app-distribution-with-xcode-4/
now: project compiles finde (via archive) i can share it. i can push the file into itunes
BUT i cant get the app on my device. i always get an error "invalid rights"
Maybe someone can help me on this.
Try using the same profile for Debug and Build and Run (as debug, not release) with the target set to your Device.
