AppManager for iOS

[Roger]

I am trying to install the AppManager for iOS and I keep getting the error "Unable to Download App". "Telerik AppManager" could not be installed at this time.

Hello Roger,

Can you please check that you have signed the AppManager mobile app with a provisioning profile specifically created for it? If you use a shared provisioning profile with an app you develop, such errors and problems are expected. You need to go to the iOS Dev Console and create a new AppID and a new provisioning profile for the AppManager mobile app. Sign the app in the Settings menu with this newly generated provisioning profile and there should be no problems.

The most probably cause here is that you have previously installed anther app (your app) that was signed with the same provisioning profile and the iOS won't let you do that for security reasons.

Can you please create the new appid and provisioning profile and get back with the results.

I will...thanks

I just created a new AppId and Provisionng Profile specifically for the AppManager. I then signed the app under settings with this new provisioning profile and resent the app to my users. When attempting to download the app I get the confirmation to Cancel or Install. Upon clicking Install the same error is displayed within a few seconds.

Hello Roger,

Normally, such errors are caused by the iOS caching app ids that it decided are not good for some reason. In such cases a completely new App Id and provisioning profile fixes the issue. Perhaps, in your case there is something more. Can you please clarify if this happens only on your device or on all of the devices of your users? Also, what versions of iOS are you trying to install the app on?

The only way of investigating this problem would be to connect a device to a Mac and get the error logs while you try to install the app and it fails. If you have a Mac, you can connect your device, open XCode and go to Window -> Devices. There is a small triangle on the bottom of the window that opens the console. Once the console is opened, try installing the app and see the error log that the iOS reports. Sending us this error log would greatly help us understand what exactly is happening on your end.

There are a couple of other things that you can try.

1. Try installing the app from another network. There is a slim chance your network is blocking the app download somehow. Of course, if your other users are using different networks and still cannot download the app, it means this is not relevant.

2. There is still a chance that iOS cached something and ignores the app install. There is one unofficial way to "free" the cache. It's not user friendly and you need a Mac, but you can still try it out:

• Download iExplorer (http://www.macroplant.com/iexplorer/) or its free version iBrowse (https://www.ibrowseapp.com/) on your Mac.
• Plug the device in the Mac machine
• Delete all files in “Media > Downloads”
• Restart the device.

The main problem with such iOS problems troubleshooting is that Apple are not giving us any chance of control over this workflow for security reasons. We would love to be able to log these errors on our side. Let me know if you have a chance to try one of these suggestions out and if yes - let me know the results.

I am looking forward to your reply.

I originally tried on multiple devices and had the same issue. I have not tried other devices since creating a new AppId and Provisioning Profile. Let me try this on another device and I will get back to you.

 Thanks.

This appears to be a solution to installing an application through the AppManager.  I can't get Telerik's AppManager to install on my iPhone.  I keep getting the error "Unable to Download App. "Telrik AppManager" could not be installed at this time."  This is keeping me from getting to the point of installing applications that have been pushed out through our Private App Store.

Hi Bradley,

This is a generic error message returned from the iOS system and can be caused for a number of reasons. Check out our AppManager Troubleshooting Page for hints what can cause this problem. Most probably, the device is not provisioned in the provisioning profile or the provisioning profile is already used by another app.

I hope this helps. Let me know if you still can't identify the problem.

The information on the troubleshooting page all seems to pertain to applications published in AppManager failing.  I cannot get Telerik's App Manager to install.  It is a Telerik AppManager that is trying to install through a browser since the Appmanager App is not available on the app store.    Please help.  I can't even try to install our private published apps due to not being able to install Telerik's AppManager.

Hello Bradley,

Due to some specific limitations, we can't distribute the AppManager mobile app through the public App Store. Instead, we distribute it over-the-air and require you to re-sign it with your certificate and provisioning profile. This makes the AppManager mobile app signed with your identity and distribution method and is subject to the same troubleshooting specifics.

The process of re-signing the AppManager mobile app is described in this article. In short, you have to generate a new appId in iOS Dev Center, generate a new provisioning profile and provide it on the Settings -> iOS page in AppManager. If you are using an Ad-Hoc or Development provisioning profiles, you will have to also register all device UDIDs in the iOS Dev Center and add them in the provisioning profile. This is the most probable cause for the error you are receiving - your device UDID is not provisioned in the app's provisioning profile. The iOS code signing specifics are described in details here.

The other equally probable cause would be that you haven't generated a new AppId and provisioning profile for the AppManager mobile app and use the provisioning profile for another app.

I hope this helps you to identify the problem. Let me know if you need further assistance.
