Commented Unassigned: A DLL is required [25332]

Hi everyone,

I'm getting this message(please see attached .JPG file) everytime when I try and install the virtual router.
I'm running on windows 8.1. This message appeared when I had windows 7 as well.

Is there a .DLL file I can download or something?

Please provide hyperlinks if possible.

Thanks.
