Well, I don't use UpDox, so I cannot comment there.
VIPER is found at
www.medwaresoftware.com.v5 should not require any username or password and should not be a demo. It actually interfaces with AC. What goes in AC is in VIPER and vice versa with the exception of combo vaccines where Pentacel goes in as one DTap-IPV-Hib rather than splitting them.
