Must run on Windows PC. Not server, just regular PC. Win 7 or win 8+.
Low cost or free. ( less than $100) (Rules out VSS)
Easy to install. No need to configure ports or firewall settings.
Self contained. No server or network access required.
Must include database. (Like Darby?) No separate database install.
I had an application like this 20 years ago that ran on DOS. What are the current options?
