I can not install apps to iphone

The iphone app developed in XCODE to tester using AdHoc has been attempting to distribute from the WEB, but it does not go well.

When i try to download from iphone, "you can not download the App." ** Is currently not available for download "" become, as well as how much "Retry", do not proceed. App that you are trying to download the icon is displayed, but remains "waiting".

Very in trouble. I tried to be heard to Apple developers, but they also looked unfamiliar, is helpless.

By the way a variety of certification documents, provisioning files, and the like is that with no problem.

Please help someone.

App development environment is OSX EICaptan10.11.5 XCODE 7.3.1.
