I'm not sure.... W8 is fairly new so consider yourself a beta tester.
Let us know how it goes. I'm thinking it should..... at least I would hope so. I've installed software in the past on the "newer" OS and it worked fine..... but there comes a point where it doesn't, and that is mostly in the drivers that are for the interface.
I had an upgrade where the software from Cake worked but the interface drivers were not compatible and the company that made the sound card had no intention of updating the drivers to the new OS.
