Shannon advised me to simply close out the unreadable screens, as the install process should have been completed at that point behind the scenes. I did so, at which point the primary screen indicated that the install was completed, then moved the license file in place, and the product is now operational. Note that this issue occurs after you have to say "yes" to the license agreement, but before it says that the product install is complete. I still suspect a font issue, so probably our default font sets do not match what your install product is expecting. I would think that a very basic fixed font would be appropriate.
