Unreal Engine 4 is available for Win10 UWP app dev now

Have you tried these things:

  • Enable Developer Mode in the Windows Settings
  • When adding the certificate (double click on the certificate), select “Install Certificate”, then “Local Machine”, select “Place all certificates in the following store” and when browsing, select “Trusted People” and continue. Just adding the certificate with the default options might not be enough, this is just how I’ve always done it.
