Dragon Naturally Speaking 10 installation problems

Hello, I'm new to the "community" and blogging (is this considered blogging?).  

I recently purchased Dragon NaturallySpeaking 10 - Preferred.  I read the issues with Vista 64-bit OS but also that this problem had been corrected.  I followed the installation instructions, turned off my antivirus and then clicked to install the two software packages needed: Visual C++ Version 8.0 and PowerMic Microphone Drivers.  I can't get the Visual C++ Version to install.  Instead I get an error message stating: "Visual C++ Runtime for Dragon NaturallySpeaking is not supported on 64-bit OS and can not be installed."

I know that Nuance came out with a DNS 10.1 upgrade to fix the 64 OS problems, but I can't download it until I load the DNS 10...which I can't do because of this Visual C++ problem.  Has anyone run into this and can provide a solution in very elementary terms?  If anyone can provide some insight, it would be greatly appreciated. 

I don't know if this matters but I have a Dell XPS M1330 Laptop.

Thank-you
