The I Believe Bible is an application developed by Legends of the Faith to run only on the oldest Windows platforms. If you're computer runs Windows Vista or a newer operating system, you can try the Compatibility Mode in order to open it. Right click on the program icon and go to Properties > Compatibility tab. Check the Run this program in compatibility mode for box and select a compatible operating system from the drop-down list. Click Apply, OK and then right click again on the launcher and select Run as Administrator. If it doesn't work, I recommend you use other similar application from Software Informer database.
