I downloaded the current version 18.104.22.168 today without ever having installed DVDFab before.
When I start DVDFab it immediately gives a messagebox:
Report - New Version Available
Current version: 22.214.171.124
Latest version: 126.96.36.199
This is a fresh install - and if I look in my Uninstall or change a program (I am running Vista 64 bit) it shows the application as 188.8.131.52
I reinstalled DVDFab again anyway and same issue.
