Anyone jumped on this version and installed it successfully ?

I have installed it on 2-machines.

Machine #1. My personal machine seems to work fine. I installed everything
but the SDK stuff. Ran a complete backup. No problems.

Machine #2. Tried the same thing. Reboot after the install CRASHES - STOP
7F - UNEXPECTED_KERNEL_MODE_TRAP.

Had to reboot SAFEMODE and go back to the LAST KNOWN GOOD CONFIGURATION.
Booted up - completely uninstalled the previous version. Tried it
again......Same crash !

Any suggestions !
