Adhoc App Fails to install on the device

Question

I have iPad which is on iOS 5.

Today I have started getting error message saying :"iTunes Sync: <<AppName>> failed to install"

Because of this I am unable to install an adhoc app.

Please help.

Answer 1

Problem solved!

It turns out that we were using the wrong Entitlement.plist. Ideally this file should have 3 rows, whereas the one which we were using just had one row.

Answer 2

Please refer to:

Why does an ad hoc ipa fail to install on one device, yet succeed on another with the same iOS version?

It has a comment by the questioner(Alyoshak) says:

Problem solved. Device id was missing from provisioning profile. I'm leaving the issue here rather than simply deleting it bc it might help others. Must add that iTunes used to give a more specific message when this occurred, and since I had not removed the device id from the list in the iPhone Dev Center (have no idea how it vanished) I didn't consider that this cd actually be the cause. Hope this helps someone misled by the vagueness of the error msg.

This might be the reason where in you might have deselected device Id from the profile.
