FYI I can install the regular ATI Proprietary driver without fail. I was able to activate the non post-release-updates version and after reboot it was active. I then tried again to select the post-release-updates version and this time no crash; it downloaded a few things and then that was it. No installation, no reboot message, etc. just sat there. I rebooted and it still wasn't active. I then was able to activate the non post-release-update version again.
