Cannot run IOS game on other devices. URGENT!

I am currently building an IOS game, using the latest version of Unreal, and every time i cook my project and make it to an IPA, add it to iTunes and run on my device it works, but i wanted to run it on other devices, but every time i do so it fails.
I updated the other devices’ UDID in my Apple Developer Account, i then re-exported the provisioning profile with the devices and added it to Unreal , but it still does not launch on other devices.
Any tips?
Thank you!

Hi Ash, can you post your log with the failure message please?

I had this same problem I think because I created and new provisioning profile with a different name and I figured out that it was still using the old provision profile. If you used a different name try deleting the old profiles from - C:\Users\user name\appdata\Local\Apple Computer\MobileDevice\Provisioning Profiles.

I removed all of my old provisioning profiles and exported a new one, but after i have done that it gives me the following error message:

I think i’ve understood what’s the problem. When i go in iPhonePackager.exe in the DOTNET folder, it has a yellow check next to the “Import a mobile provision”, and it says the bundle identifier does not match my project . Do i need to change that in the Apple Developer Website?

I fixed it!
I had to copy my project name and Bundle ID from the App ID section in the Apple Developer website.
Thanks again for all of the help.
