Q: When I try to update RTG Bills or RTG Timer, I get a message that says, Bad install command: . . . You may need a newer version of RTG Update.

A: RTG Update is the program that installs updates for RTG Bills and RTG Timer.  This message means that you need a more recent version of RTG Update. Check to see if an update to RTG Update is available. (RTG Update can update itself when a new feature is added.)
