Apps not installing, common causes and solutions


There are a number of reasons apps might not install on iPads.  This article lists a few of the causes and solutions to help with troubleshooting.


Problem:  The app being installed is 32-bit and not compatible with iOS version that requires 64-bit 

Indicators: The app will not install and status will indicate 32-bit app

To diagnose: Status in Control Tower shows old sync date and/or pending.  Try screen lock or app lock on the iPad from Teacher Tools to help determine if the device is communicating with TechPilot.

Solution: Make sure the device is on and awake.  Make sure the device is connected to the internet.  Hard reboot iPad (Hold power and Home button until it resets).  If all else fails, you can try to delete the iPad from Control Tower and factory reset.


Problem:  Out of app licenses

Solution: Go to VPP/ASM account and purchase more licenses of the app.


Problem:  Firewall is blocking install

Indicators: Apps won’t install, but there are no indicators in Control Tower

To diagnose: Create hotspot outside of the school network or take the device outside of the school network to connect to the Internet to see if apps start installing properly

Solution: If the apps install when connected to an outside network, check the settings on the firewall to allow communication from Apple and TechPilot


Problem:  The app is no longer available in the app store.

Indicators: Sometimes will receive an error message in Control Tower stating the app is no longer available.

If the app is device assignable, resync and enable the VPP account in Control Tower.


Problem:  iPad is unsupervised
