However, sometimes, users may find that there is a "unable to install" prompt when installing. What is the reason? You can refer to the following possibilities.
The certificate is not trusted by the enterprise signing application of 1.Apple.
When installing Apple's enterprise signature application, users need to trust settings-profile and device management-enterprise certificate in enterprise application.
In the pop-up installation boot prompt, click "Install", select the certificate (just signed the enterprise certificate), and find the newly downloaded app and trust certificate. App can be used successfully. So when you are prompted that you can't install, it may be because you don't have a trust certificate. You can trust the certificate and try to install the Apple Enterprise Signature application again.
2. Expiration/cancellation of certificates signed by enterprises
The main advantage of Apple's enterprise signature application is that the Apple application can be installed directly, and it does not need to be put on shelves or audited. But the disadvantage is that the stability is weak and the signature is easy to drop. After the signature is discarded, the installed users can't continue to use it, and new users can't install it. They must re-sign before installation.
At present, Apple's corporate signature is mainly based on the developer service platform, and the signatures provided by the platform are generally charged monthly. If the fee is not renewed in time, the signature will be invalid.
3. Network reasons
It is also possible that the installation failed due to network reasons. You can turn off Wi-Fi to the mobile network or switch Wi-Fi, turn on airplane mode and then turn it off and try to reconnect, or install and download using the mobile network.
