I had to reinstall VS2010 at work and because I clearly didn't think this all the way through, forgot to save my autoexp.dat file before removing the old installation. And of course I didn't realise what had happened until I had to dig deeper into some Qt GUI code that wasn't quite working as expected, and of course I was prompted with the raw data.
Fortunately a quick search on Google led me to this page Human Machine Teaming Lab | Knowledge / Qt that contains a very comprehensive set of visualisers. I'd highly recommend them if you're doing any sort of work with the Qt libraries. Just keep in mind that the Qt visualisers are for Visual Studio 2008 and 2010, so they're anything but guaranteed to work with newer versions.
