We have Vista Enterprise here.
We've downloaded ZoneAlarm Internet Security Suite v7.1.078
and it seems that there is a problem with the installation.

We've installed in the Virtual PC with Vista Enterprise w/SP1 and it works.
But when we install it on the actual PC (Core2Duo and Core2Quad), the installation does not behave properly.
It would freeze the screen like a snapshot and we cannot browse or move around in the desktop.
The menu bar works, but when you select the program on the task bar, it's like a screen shot and cannot do anything.
Interesting, when we boot into Safe Mode, the installation works.
Restarted the computer into Safe Mode, the ZoneAlarm program doesn't come up, but it is running in the background--services.
After successfully installing in Safe Mode and booting into regular mode, ZoneAlarm does not come up at all.
The service is running the background.
There is no way to bring up the program to modify the settings and stuff.
I've spent ALL WEEKEND just to figure what the **bleep** is going on and the problem is pointing to ZoneAlarm.
ZA works fine on Windows XP Pro SP2 and single core PCs...
But when it comes to Core2Duo and Core2Quad with Vista Enterprise, it doesn't work properly.
It would be nice if the folks at ZA would get the actual hardware to test out instead of running the tests on VMWare or Virtual PCs.
