When changing file ownership to allow me access to a hidden log file, something happened that removed installed apps from the app store. They are not on the start menu, nor are they shown among "All Apps". I did some digging around and managed to find the folders these apps are stored in, but have no idea which file launches each app. I went to the App Store to reinstall them, but in each case the App Store told me I already have it installed. Any information as to what I need to do to gain access to these apps would be much appreciated. Thanks!
