IIS 7.5 asp.net application not running

Question

My asp.net MVC application not working in IIS 7.5 on Windows 7, but it's working fine in IIS 8 with Windows 10.

In my live server I am facing the same. In my server I have Windows 2012 r2

I was creating a demo application, but faced the same issue.

Anyone had this issue?
