Hi Everyone, My developer sent me an .ipa file to load onto my iPhone 5; however, the app won't install on my phone. I get the same error all the time "Unable to Download Apps: The app could not be installed at this time" Can anyone tell me why this is happening? This is my first time doing this and your help is much appreciated. Thanks, Andrew

How are you trying to install the file? Here's some ways to do it via Xcode or iTunes: http://stackoverflow.com/questions/14127576/install-ipa-with-itunes-11 But, before you do that, you need to make sure your device is registered on your developer's ad-hoc distribution list. Did you give him your device UDID number?

I did give him the UDID number. I tried installing the file from iTunes and tried installing it by tapping on the link the developer gave me.

Have the developer confirm the UDID, and ensure it's correct. Otherwise, it'll never work. If you have the proper device UDID in the provisional profiles, it should work from iTunes, or almost anywhere. Cheers! -- Smug

Not sure then - it's possible he didn't set your device up properly in his Apple developer account.

Right, but if 'everything' is not correct, it won't work. That said, if it's not working, then 'something' must not be correct. Since the UDID is about a mile long, that is always a possibility. There are several free utilities in the App Store that will obtain your UDID and allow an email to be sent to the developer. If that's how you provided your UDID, that may be all that 'you' can do. The rest is up to the developer to make it correct. Cheers! -- Smug

Hi Smug, That is what I did to eliminate any typos that I may make. I am getting the developer to look at it on his end. Thank you for your help Smug and Chris1! Andrew

In my pre-Buzztouch age, I had to test an app once or twice. I don't remember if I had to give my UDID (I think so), but I remember receiving an .ipa file AND another file (a certificate). I had to add both to iTunes to install the app. Don't know if it's still that way!

Do NOT use an app on the App Store to retrieve and send your UDID code. Apple dis-allows apps to access the UDID code for User Privacy reasons. The app will still get most of the UDID code, but Apple puts FFFF in place of the leftmost digits of the UDID code. Instead, connect your iPhone to iTunes. Click on the name of your iPhone in the left sidebar. Click on the General tab. Then click on the Serial Number to switch it to UDID code. Then Edit menu, Copy. Then email to the Developer for a new device to be registered and to be added into the Provisioning Profile. -- Niraj
