Access Gateway installer is hanging at 13% progress. A previous installation got damaged, so a re-installation is being attempted.
Presence of zerog registry files can cause the installation program to fail. As these are hidden files, appropriate options are needed when searching for them.
Search the file system for any files or folders with the string 'zerog'. Please note these are hidden files and may not show up depending on how you search. Delete these files/folders before retrying the installation.
