Received alert to update from ZASS 7 to 8.
Downloaded and installed.
When computer rebooted, first Windows splash screen came up, then went blank.
That was it.
PC was on, no video, no drive activity.
After 10 minutes did a hard shutdown and restart.
Same thing happened until I booted into safe mode, uninstalled 8, reinstalled 7.0.483.000, which works just fine.
Installs of 22.214.171.124 on several client computers went just fine.
