iOS PreflightApplication: The application has already been installed

[Lextar]

I have a problem with my app when I use "Build and Go" with my iPhone. When the application is already installed on the phone I get the following message:

Your mobile device has encountered an unexpected error (0xE8000036) during the install phase: PreflightingApplication

In the organizer this is what appears in the console:

Sun Oct 12 22:57:05 unknown mobile_installation_proxy[334] <Error>: preflight_application_install: The application has already been installed
Sun Oct 12 22:57:05 unknown mobile_installation_proxy[334] <Error>: install_application: Could not preflight application install
Sun Oct 12 22:57:05 unknown mobile_installation_proxy[334] <Error>: handle_install: Installation failed


When I uninstall the app first I can use "Build and Go".

Is this normal? I recently added a settings bundle and now I have to

1. Uninstall the app from the iPhone
2. Re-enter the settings in the settings app
3. Press Build and Go
4. Debug

I just want XCode to update the application after I add a few lines of code.

What am I doing wrong? I searched a lot in google but it seems like I'm the only one having this problem.

It does work when I try the same in the iPhone Simulator.

Thanks for your help.

I found the problem!

Somehow my Development Provisioning Profile wasn't on my mac anymore. I downloaded it again and drag&dropped it on the XCode dock icon.

Now I can use "Build and Go" without problems.
