Ok I was bored looking for things to do, when.....
My wife used to use my Mac as another user with a profile to her own home account on the same machine, she then bought her own Mac Book, and I deleted her profile on my Mac. The app Store icon never really came to terms with this and was always showing updates required although I could access as her profile was long gone. Irritated by this for some time I decided to "Fix" this annoyance.
My conclusion like most, was to delete the "App Store" app, with the intension of re installing it. I cant!
Sorry for the long story, but if anyone knows how I can reinstall the App Store, without a degree in computer programming, I would be very grateful.
Thanks in advance
