Unreal Engine 4.10 failed install. R-1603

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]


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.

Hi BlueOwl,

I’m sorry to hear that you are having issues. Thank you for the logs. Could you also send us your debug logs and dxdiag? Steps on how to get this information can be found here.

Hi BlueOwl,
