So if your Mac did not come with HyperCard Player 2.2 or 2.3, you can use HSP Pro instead. Pro is an upgrade of my previously released Hyper-Stack Player 2.3.
Some features require a registration code for activation.
HSP Pro provides a good way for school computer labs to provide access to their HyperCard stacks. A password protection scheme prevents the students from making any unauthorized changes. This file may not be on every server.
