Read the docs... or install it and test it.

If its an important machine... then read the docs.

I installed software on a new server (wasn't important, as it was just in setup phase) and it crashed the 2k3 server all together. It was outpost firewall. I had to reload the whole thing. Recovery, last known good, etc couldn't recover it.
