Getting error while installing .ipa file and provision profile through iTunes on another ipad and mac

Question

I am adding devices UDID into provision profile and sending this to other mac for installation on another iPad. If I try to install .ipa through iTunes on that mac, it gets an error "The iPad could not be synced because this computer is no longer authorised for purchased items that are on this iPad" but this computer is already authorised.

Answer 1

Why don't you try using Xcode in installing the .ipa in the device? Open Xcode then Go to Window>Devices. Select your device then click the '+' button in the bottom. Select the .ipa file.
