Unfortunately, Sony USA does not provide any support pages for downloading included utilities and they seriously frown upon any persons or sites that provide downloads of such software. You may want to privately contact other TR2 owners for the necessary software or contact Sony to see if they will ship you drivers of a CD/DVD (which I doubt they will do).
Once you do get the drivers you need to know that there are a lot of little tricks that one has to do to successfully install the Sony apps. One of our members has put up his experience on how to get a successful installation. You can find it here .
