That runtime library is apparently required in order to run programs written in Visual-C language.
I’m a Mac guy, so I’m not qualified to give any advice about Windows. But in my opinion, seeing the web browser attempting to execute a Visual-C program is not a good thing.
I was going to google that up so I would have to bug you anymore with, "what is."
Both yahoo and google are gone now. I'm going to have to bring one of them back.
