While on my way to search the Web for new things, I came across something very common but weird and unusual, users were actually asking for Offline installer of .Net Framework 4.5, because when they try to update the .Net Framework, they receive an error saying the .Net Framework 4.5 cannot be installed, Please contact your Administrator. While there are applications who demands nothing less than .Net Framework 4.5, those who can’t able to install it are in deep trouble. So, a little bit more search helped me in finding the solution of this problem. One thing that i hate is the people out there don’t search official sites much, they mostly rely on third party and thus can’t able to make things right on time.
