Ok, so I am writing all my steps here:
Replace Iphone Packager for the one you posted here
Assign 4.10 project for certificate
create certificate request
type email and common name as self email and as company
generate certificate and key pair
Go to apple developer
Create a Certificate for production (Appstore and Ad hoc)
upload csr file, generate and download
Create provisioning (distribution appstore option)
Select bundleid and certificate
Download
Close IphonePackager
Open UE4 4.10.4 as admin
Deleted previous provisions from Appdata/Local/AppleComputer folder
open project
Imported provision (Get No Valid Certificate Found atm)
Reimported certificate and key pair
Status of provision now says Identifier not matched as it is currently com.UpARiverDream.UpARiverDream
Change to what matches to itunes connect (UpARiverDream), says now valid in provision.
Try to package now
Get Provision not found again.
I package anyway so you can see the full log. Hope this helps you find the issue.
