Hi there!

I’m having some problems with installing UE 4.10.

“The necessary prerequisites have failed to install. Error code R-1603.”

I’ve already tried restarting the PC and running the installer with full admin rights.

Here’s the [installation logs]

Thanks!

Thank you for providing the logs. Looks like there was an issue installing DirectX. We don’t have a workaround at the moment but will reply back as soon as we do.
