A legitimate concern: Since Windows 7 no longer receives security updates (unless you pay for ESU), is .NET 4.5.2 safe?

Cause: Missing prerequisite updates (SP1 or KB2919355).
Fix: Download and install KB2919355 from Microsoft Update Catalog manually (requires internet, but you can do this on another PC and transfer the .msu file).
