error message that apple configurator "can't install app", tooltip that "an unknown error message "install prohibited" was received from the device".

 

Computer is authorized, app is free (iwritewords free version), ipad is supervised.  Have tried multiple apps, clearing and restoring supervision, clearing and restoring apps from configurator.  same error everytime.

 

Trying to determine if it is viable to deploy iPads as childrens games stations in public library branches.


iPad 2, iOS 5.1.1

    Are any restrictions at all  enabled on the iPad?  If so, remove them and try again.

    restrictions or no, makes no difference.

    Try unsupervising , and installing app(s) just using prepare function.

    unsupervising, which cleared the device, and configuring the prepare setup to include the profile and apps works. 

     

    However this would be tedious in real-world application as I would have to, in adding new apps to an iPad, unsupervise, supervise, activate the iPad again (language, country, location services etc.) and setup the restrictions on the device again.

     

    This can't be how it is supposed to work.  Shouldn't I be able to add an app to an existing device through configurator without having to unsupervise the device and start all over?

    Hi I have just finished struggling with this issue. The problem was that I had a profile set up for our students which had the "allow app installs" unticked. You would think that this would just stop the user installing but obviously it blocked it on the ipads completely. I suspected this so I created an "Installation" profile which only had the web proxy configured everything else was left as default. This didn't work! It was only when I realised that I had to go in and tick the allow installs box that it sprang to life. Cheers Apple that's two days that i won't get back.

    Just in passing, whilst I was preparing the ipads I was getting an "ios file invalid" error message with no explanation. Turns out that Apple configurator needs a live internet link which, working in school, I didn't have until I logged on. I think that's there's still a long way to go before Apple gets it right for ordinary schools.

    I'm just beginning to learn all of this, and was struggling with the same issue. I tried all of the things listed above, to no avail.

     

    Finally, I found something that worked for me:

     

    In Settings -> General, near the very bottom, there is a "Profile" that shouls be whatever you installed via Configurator. Delete that, and then re-prepare the iPad.

     

    That worked painlessly for me.

    You should be able to be able to accomplish the same by selecting "erase before installing" in Configurator and you can add new apps to the profile you are using or remove, whatever the case may be.

    Thanks for the tip. This helped me.

    The problem with unsupervising and re-supervising is that I have to start all over again with the "new iPad" start up.  I have to tell it what language, what id to pair it with and such.  This is no way to maintain ipads!!!

    If you have "Allow App Installs" Checked so that Students cannot install apps, you need to Untick "Allow App installs", then click the Apply button BEFORE you choose the apps to install. For some reason, Configurator will fail installing apps, and then neglect to apply the new configuration. This should all be documented better by Apple, instead of us having to figure it out.

    This is exactly what I've found out.  Thank you for stating it so succinctly.

    I am getting the "Can't install apps" error. I have tried the following:

     

    • Unsupervise, resupervise
    • Delete profile
    • Erase all settings on the iPad and start from scratch

     

    I'm using Lion with 1st gen iPads and Apple Configurator version 1.2.

     

    Basically, my iPads with configurator right now are useless. I can't install any apps. Anyone have any ideas?

    What a big huge hairy deal. I had the same problem and came here to find solutions. Based on what was said, this is what I tried and what worked for me...

     

    Even though I had the setting to remove profiles that AC didn't install, I checked the profiles and the student restrictions profile that prevents installing apps was still on there. So I guess even though I'd unchecked it, AC didn't remove it. I consider that a bug. But I digress...

     

    I manually removed every profile on the iPad directed excect the one that says it's supervised and then refreshed in AC. That worked. So I won't have to uncheck and recheck all apps (which I tried and didn't work for me) but I *WILL* have to manually remove that student restriction profile on every single device. Grrr!! I'm considering NOT putting that one back. The iTunes store is blocked in our district filter for students anyway. I can't imaging having to manually remove that profile on every device every time I want to add a new app or update. Insane.

    I tried that. It didn't work. I had to remove some things which I couldn't even find without using the terminal. However, now it's unsupervising my devices when I plug them in automatically and I have to prepare them all again. I'm ready EXTREMELY frustrated with Configurator. I feel like it's extremely buggy and rather shoddy. Not what I'd expect from Apple.
