Unable to Download App + App is No Longer Available

问题

We have an app that was distributed using Enterprise Distribution Profile. Now, the same app is working for some but others are reporting the following issues.

Existing/Installed app throws this error, and doesn't open:

{App Name} Is No Longer Available
Users who try to download the app from the Enterprise link are reporting this error:

Unable to Download App - {App Name} could not be installed at this time.

Done Retry

Users running iOS 8.4.1 are specifically reporting these issues. I regenerated the profile and rebuild the app. This seems to have fixed the issue for some users, but not for all.

What's the real problem here? Thoughts?

Most common causes of this issue:

URL in the plist that references the ipa is invalid.

Device storage is full

The provisioning profile is a developer provisioning profile

The ad hoc distribution provisioning profile is corrupted and the device is having an issue with it.

The device was restored from a backup and is causing a conflict for over-the-air distribution

There was a network timeout

Architecture settings of the build and the device are incompatible (can sometimes happen when "Build Active Architecture Only" is on when building).

Not Using Mobile Safari.

To find out the exact cause of this issue:

Connect the device to your Mac.

In Xcode, open the Devices window.

Choose your device from list on the left.

View the console for the device.

Now install the app it will show the exact cause of problem

My guess, since it is only happening on some device, is that you could be using a developer provisioning profile, or maybe you are building for only one architecture, so it will only work on some devices that match the built architecture.

Please look at the device console during an install attempt to get a detailed error that should point you down the correct path for a fix.
