iOS ad-hoc build not installing on device

I have created an ad-hoc build for my app and I have added the UDID's of a couple of devices in the iOS dev centre. It seems that the app installs on one of them but doesn't on the other. Is this a common problem? Am I supposed to do anything else other than just adding the UDID?

Solution

I hope that, you forgot to add the Provisioning Profile which has added(UDID) into it.

Include the Profile to the App and then choose the same while creating archive of it
