After i tried to update DVDFab 9 i got a problem.
When i try to install DVDFab 9 (or 8 for that sake) i get an error message.

Can't install because of unknown error - get help from the software producer.

I tried a fresh install, and uninstalled the version i had, but it didn't help.

Help me, please, because now i don't have any DVDfab installed.
