Moved this to SecurityCenter as a more appropriate spot to get help.
It is compatible with Vista SP1 and upwards, preferably SP2 of course and both x86 and x64 versions.
What it may not be compatible with is other security software that is or was installed or an unpatched version of Vista...make sure that all updates are installed, including those for parts of the system you may not use (IE for instance, but you can ignore language packs in Ultimate version of course).
