'NUnit 126.96.36.19954' already installed.
Access to the path 'D:\tfsProd\Sec-ClearedVisitor\ClearedVisitor\packages\repositories.config' is denied.
Tried to add a package to 'D:\tfsProd\Sec-ClearedVisitor\MvcUtil and I got the above message.
MvcUtil is a shared library. It's shared by the MVC project ClearedVisitor. I don't why nuGet wants to open that file.
I checked the file out and checked the properties and still get the message.
