Troubleshoot iOS App Installation Failure

When the iOS private test application is installed, the common reasons for installation failure are summarized as follows for everyone's convenience.

When the App starts, the message "cannot be installed", "cannot verify", "Installation failed" is displayed, or the dark icon is displayed

This reason is basically caused by incorrect App signature. To continue installing such apps, you will need to use the Apple Certificate Customization Service.

Startup Tip: Untrusted enterprise developers

Please return to the iOS system desktop, and then open Settings - General - VPN and Device management, and then click the corresponding description file to enter, and then click the button Trust. For details, see: Run Enterprise application

Startup Tip: To enable Developer mode

In iOS16 or later, you must open the developer mode when installing the iOS application of Adhoc. For detailed instructions, see: Enable Developer mode

If you are an App developer, you can check:

• Whether the signature mode of the App is correct
• If the App uses Adhoc mode, then the description file is correctly added UDID
• Whether the certificate is expired or revoked
• Whether the App supports the corresponding Architecture
• Whether the App supports the corresponding iOS system version
• Whether the App supports the corresponding device type (e.g. iPhone Only cannot be installed on iPad)
• Whether the updated version package is the same certificate as the old version

Have you tried the above solution, or can't solve it?

If the problem still cannot be solved after checking according to the above methods, priority can be given to the App certificate problem, because this problem is the most common type of problem that causes App installation failure. You can use the Apple certificate customization service to solve the problem.
