Hi 0xFAN, Sorry you are running into the issue. Thanks for providing the logs though, super helpful in pinpointing the problem. There are similarities between your issue and the issue the original poster is having but the underlying cause seems to differ which is why we typically prefer a separate thread to be started. Your issue is similar because you are seeing the R-1603 error code. This tells us that the prerequisites installer failed. Further investigation of your logs shows that DirectX failed to install. This is also similar with the original poster. The difference is that your DirectX install failed with code: -9. We’ll look into better relaying this info to the user in future releases.
We have seen DirectX return code -9 in the past but finding meaningful info on why it would return -9 has proved rather difficult. The short answer is that I don’t know. Yet.
As I posted above, we don’t have a workaround with the current launcher setup. I will add something that will let you bypass the problem. It will be available next launcher release.
