@ Sinda, Yeah, I saw that blurb about Win7, but I'm using Win8 and I saw that the launcher was OK to use with that.
I D/L'd a copy of the file and installed it manually and was able to play NP, but I'd still like to get this issue resolved so I can switch back and forth with other mods when I want to.
EDIT: Just for the H of it, I D/L'd the "EasyFix" tool, thinking it might help, but upon trying to run it, I received the message that the tool was not for my OS and it did not run.
