What do you mean by it "does not run"? Do you have some problem with
it? If so please explain the problem? You can always turn
hyperthreading off in BIOS if this is your problem, but I have never
experienced a problem relating to hyperthreading.

it is a superserver.

There is a big difference between multi-cpu and hyperthreading!

It does run on multi-cpu, but because of the way it is written and the
way windows works, windows can spend a significant amount of resources
bouncing the process between the available CPUs. The CPUAffinity mask
can be set in the firebird.conf to counter this.

I don't see why not. But again if you have specific doubts or
problems, then I would be interested to hear them.
