Error Code R-1603. The necessary prerquisites have failed to install.
I have Windows 10 installed and Visual Studio Community 2015 with update 1. But when I installed the launcher with the MSI file, it downloads the files, and then after please wait: Error Code R-1603. The necessary prerquisites have failed to install.
I need help! Nothing of the solutions from posts worked for me! :(

I have Windows 8.1 installed but i do not use Visual Studio Community. I have installed UE 4.10 and when i wanted to update to 4.10.2 i got the same error: Error Code R-1603. i found a solution here: https://answers.unrealengine.com/questions/337793/unreal-410-installation-error-1603-with-log-detail.html
You can also try right clicking the Epic launcher shortcut and selecting "Run As Administrator"
This works for me.
