If the progress is near 99% when it fails, just create a shortcut to c:\program files(x86)\ticket\ticket.exe and run directly from there.
Make sure a version of TICKET isn't already running. Try restarting your PC and try again.
If that still fails, HEXCOM Support can provide a version of TICKET that does not need installation and all files are in one folder
and can be run directly from that folder.
