It is a simple as that I installed glimpse following this page. :
http://getglimpse.com/About/QuickStart
I then attempt to navigate to http://myApp/glimpse
http://myApp/glimpse
I had a multi-project solution and was installing it from the Package Manager Console. I found that installing it using the following command worked:
PM> Install-Package -ProjectName Glimpse.MVC4
Of course you need to replace with your own project name.
