Windows 7 'this file does not have a program associated'

Sometimes you get an error message when you try and open up some folders that the association is missing. This may be from some corruption in the registry or OS.

I solved the problem by going here

and then following Whizzkidraj's instructions. He points us to here

which is a file association index page. I clicked on Folder (because this was the area of trouble for me) and then downloaded the .reg file to the desktop. I right clicked on this and then merged it with the registry and then folders would open as they should.
