Development for iOS. Why does the app freeze when installing an .app file via iTunes?

Question

iOS

There is an application - I did not do it, it seemed to work before. Something had to be redone. Remade.
Registered in the iOS Developer program on the Apple website, paid. Further, he seemed to do everything correctly, including entering the UDIDs of the necessary devices.
It works on the emulator, it starts from XCode on devices. When trying to install an application via iTunes (should be sent to the client to view), the following happens:
1. A dimmed application icon appears on the desktop of the device.
2. In iTunes, the status "Installing" is stuck on the installation button.
3. When you try to click on the icon, the name of the application changes to "Installing".
4. Everything. Nothing further changes.
I tried it on three different devices - on one (iPad with iOS 7.0.4) it worked. On everyone else (iPad Air and iPhone 5 with 7.1.1) - the picture described above.

Answer 1

I do not quite understand what it means to "install the application through iTunes." Is AdHoc build being used? Re-release of the Distribution profile often helps. Especially after adding devices.
But if the problem is with the profile, then do not install it on any device. And so, yes, SashaSkot correctly said that UDIDs were added incorrectly.

Answer 2

Have you added the UDID of the devices correctly and signed with the same provision? There is a mistake in this.
