Error code R-5

Development Getting Started & Setup

I’m trying to install UE4 4.10 and somewhere along the installation it gives me the following message: “The necessary prerequisites have failed to install.Error code R-5”
Not sure what the issue is or how to fix it.

I recently did a fresh windows 7 install so I’m not sure what the problem is.
Thanks in advance.
