Hello,

I have the same problem and did not find any relevant help. Have you ever found a solution?

Thanks a lot. Vladimir

Hello, I found a solution!
Problem is in iTunes. Please don’t install iTunes from Microsoft store !!!
IOS launch with iTunes downloaded directly from Apple site works without any problems.

Hey Vladimir Bronis ! I think you are right. The problem is with the itunes downloaded from Microsoft Store. But now i an unable to download itunes from apple’s official website, as it is referring Microsoft store only. Can you give me the link or zip file of itunes from apple website.

Not sure if you resolved your issue but I had the same problem. You can download non windows store version from the standard itunes download page, by using the links under “Looking for other versions?”.

Alternatively (and I’ve not tested this myself) there is a section in the unreal docs regarding this.

Uninstalling the Microsoft store version of iTunes and reinstalling iTunes downloaded from the Apple website fixed the build failed error for me! Thank you!

i made a bunch of tutorials to walk through how to fix all the errors when trying to launch to your ios device Unreal Packaging for IOS Tutorial: How To Fix Provision Not Found Error - YouTube granted I was using a mac for these but they should still help your issue
