Just did a fresh install of W7 x64, which I've been testing for a few weeks on my mackbook pro...works like a charm and seems to be everything that Vista should have been (not that it was terrible, just a bit fiddly).
So far, got my fireface 400 and liquidmix to work, my emu 1820 as OS audio card and even Windows' own Easy Transfer did a good job of getting all my settings across.
However, I can't get iLok to install; which could be a bit of a showstopper.
The error it comes up with is this:
(image is from someone else, but I get the same error; I am however installing the x64 version)
Tried installing as admin, with xp compatibillity, but unfortunately no go...
A shame because everything else so far works like a charm!
Cheers,
Joe
