Have you DotFuscator at DotFuscator with Visual Studio 2010? I do not know the required edition (MSDN gives only Ultimate), but I remember reading somewhere that Alvas.Audio uses it.
Like in Visual Studio 2012, I did not check, but when I install the development tools, I just install everything (even if I do not use it). Even if it is not, you must install it using Visual Studio 2010 Ultimate (the trial version will work), uninstall everything except DotFuscator, and install Visual Studio 2012.
