When I first installed NotePad++ it created a short cut (shell extension) to allow you to right click on a file and choose "Edit with NotePad++".
It actually was there and I installed the "e" trial and my "Edit with Notepad++" shortcut went away. I have since uninstalled E.
I have also uninstalled/reinstalled NP++ but that still didn't bring the shell integration back.
I also found a blog entry where someone said the the SCiTE editor messes this up to. But, I don't have scite installed.... at least it isn't on my add/remove list.
I am using Windows 7 64-bit.
Can anyone tell me why this might not be working any more?
