Hey guys,

I’m trying to get into Mobile Development with UE, but am already struggling with the baby steps. I’ve done everything according to the available guides, but seem to be unable to deploy my game from Unreal directly onto the attached iPhone (I’m trying to deploy from a Windows 10 machine to iPhone SE with UE4.15.1).

I went through the whole process using the IPP to create certificate request, key pair getting the provision from the Apple Developer platform, create an App ID and the signing certificate there and so on. All seems to be working fine, inside UE4 both Provision and Cerificate turn green and show valid (inside IPP I never saw any green checkmarks though), but when I try to launch an All_IOS it always fails to deploy.

“PackagingResults:Error: Error Deployment failed! Unknown Error”

It seems to get stuck here: “IPP ERROR: Application exception: System.Security.Cryptography.CryptographicException: Invalid provider type specified.” and I couldn’t find out what causes this. Apologies if that turns out to be an amateur question, but as mention I’m new to the mobile sector.

I did try the same process with just the standard RollingExample map and run into the same error, so it seems either I’m doing something wrong or something is wrong with my machine setup.

Any hints to point me in the right direction would be greatly appreciated!

Thanks!
