I installed HouseBot on my XP pro machine and while launching it I got an error box: "Error initializing database support on the machine. This error is probably due to missing database components. ...".
I uninstalled and then made a full installation, but still got the same error message.
Make sure you check the "Microsoft Jet Data Access Components" option during setup. You have to check it yourself. The "Complete Installation" does not check if automatically.
