Query: Older versions do not work unde Win& pro 64-bit

I own this mic (3 years+) and since upgrading to win7 pro 64-bit the mic will not work. It is not recognised and the driver fails to install. Blue support could care less, don't respond, and have not provided a firmware or driver update. My mic is now an expensive desk ornament. If you are considering buying this mic - beware how old the seller's stock is.
