iPhone app could not be installed at this time

Question

i was trying to install my iphone application from testflight. it installs perfectly on few devices but in some after installing about 80 percent it gives an error \"Unable to d

Answer 1

Here is what worked for me:

1. Clear the Cache and Cookies (Settings > Safari).
2. Remove existing profile (if any) linked to "Test Flight App" (Settings > General > Profiles).
3. Open Safari and go to https://testflightapp.com/. Login and follow the steps to start over.

P.S. I used to have a Test Flight App, but it looks like it crashed and the icon turned to be all white. Restarting my iPhone made it reappear correctly.

Answer 2

For me, just uninstall the Testflight and restart my iphone. After that, install TestFlight, it works fine !

Answer 3

I have had the same issue after fiddling around with certificates (argh).

The problem became apparent as I followed the comment of @Duraiamuthan.H, I installed on a device. The device reported 0xe8008016 (Entitlements) see SO here

The initial reason was, that the testflight target used the App store distribution certificate, not the Team certificate. I fixed that and the application was installing on the device over Xcode and then it also worked with testflight.

Answer 4

As for Xcode 5.1, the problem was in arm64 architecture in VALID_ARCHS. Building the release configuration for 5.0 device locally gives the following error:

Xcode cannot install or launch applications supporting the 64-bit architecture on devices running iOS versions prior to 6.0. This configuration is supported for distribution through the iOS App Store, but cannot be used during development with Xcode. To continue, edit the Run scheme action and select a build configuration that does not include the 64-bit architecture.

Removing arm64 from VALID_ARCHS solves the issue. In my case I had to create a separate branch for testing on iOS 5 devices.

Answer 5

Watch the console through the Xcode Organiser for the device that is failing to install.

You'll get a helpful message from the system telling you what is wrong. There are lots of potential failure reasons, so unless you check the message, you're just guessing...
