The Installation Cannot Continue

When installing Ivory II, an I/O or CRC error appears, and the installation cannot continue. What do I do?

This is the tip of the iceberg of insane failures you may encounter when installing Synthogy Ivory II for Mac OS X. I gave up on their installer and, I kid you not, wrote my own in Python. No wonder they treat me like a criminal.

All I wanted to do was play the piano. Never again.
