HealthFrame Family edition is only intended to support maintaining 12 PHRs per computer.
Through tricks - you can maintain more, but this would be awkward, and is not recomended.
If you need to maintain more than 12 PHRs, please clarify how you are thinking of using HealthFrame, and why you need to maintain so many PHRs. We are working on developing additional products that might better address your needs.
