Notes 8.5 install on Mac OS X

When I attempt to install Lotus Notes 8.5 on a Mac OS x leopard config I receive the following error message:

Unexpected results have occured during the provisioning operation.

Once I click next I am presented with another screen that says:

Run preflight script for notes 8.5 mac. Please contact Notes support.

Not sure what to do.
