Upgrade 7 to 8.5 crashes
Description of the issue
When I try to upgrade from 7.0 to 8.5 or 8.5v2 it crashes on install. My system is Mac OS 10.5.5. I've repaired disk persmissions and logged in as Administrator, but still crashes after I enter the serial number. I've installed on OS 10.4 without any issues. The serial number is correct as it displays a green check mark. Any suggestions?
