I installed this last night on my PC (I have a Polar) and so far it's been working fine. The 3rd stereo output is working like I expected it to and have not yet had the chance to fuss with the Atomizer. Regarding whether or not this will work for the other TI's besides the Snow, I c/p'd this from the download page:
Virus TI Installer 2.7.0 for Windows Public Beta 3
