Q: When I try to back up my data in RTG Bills, I get the message Zip error 12 and no backup is created.

A: This error may occur if RTG Bills or RTG Timer is installed on a network, but you are backing up to a local hard disk. To fix the problem, you need to install a newer version of RTG Bills.

Note that recent versions of RTG Bills require you to install the programs on your local disk, even if the data files are installed on a server.
