Xcode will run app on simulator but not on device

Question

I receive the following error when trying to run the app on my device.

error: failed to launch '/Users/michael/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphoneos/Word Processor.app/Word Processor' -- No such file or directory (/Users/michael/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphoneos/Word Processor.app/Word Processor) 

The app runs fine in the simulator. When I try to debug on the device, it appears to copy the app (I can see the icon), but then stalls with the above message. Xcode says it is running the app on my iPod, but nothing is happening on my iPod.

When I click on the app, the app appears to launch, but seems to be missing resources. Other projects of mine work properly. What setting do I need to change to make this work properly.? Looking at the error message, it seems to be looking in my mac for the app. But this doesn't make sense since I am trying to run it on my 4th gen iPod touch. I am using Xcode 4.3.1 and iOS 5.1

With Mountain Lion and the latest version of Xcode (4.4.4F250), none of the suggestions in this thread worked directly (clean, clean project, remove derived data folder, etc). This sequence did. From DhilipSiva:

1. Disconnect your device
2. Delete the app from your device
3. Quit Xcode (Don't just simply close the window, quit it)
4. Delete derived data folder rm -fr ~/Library/Developer/Xcode/DerivedData (console)
5. Start Xcode,connect device & run the project
