The necessary prerquisites have failed to install. Error Code R-1603

I’ve searched alot and tried alot. None of any solutions helped. From simple running as admin to working on my windows updates. There is also nothing said about “Error Code R-1603” at the troubleshooting.

Anybody got a solution?

Edit: I also can’t install newer version of Epic Games Launcher. Luckily I got an older Install msi. I can log in but still, outdated and can’t update.
