I just went through the whole installation process and as far as I could tell there weren't any installation options. It just set off by itself and installed everything where it damn well wanted to. As a result, not only did it install the .dll to the wrong folder (which was easily fixed) but I have no idea where the samples were installed (I would have liked the option to install them on my sample drive). Can anyone shed any light? Did I miss some installation options here? 

OK so I just read the following about installing to a separate drive:

It says you have to start the online installer and in the "advanced" tab there should be options to choose a new path for the install. So I did this, and it moved the install to my sample drive. Question though: am I right in assuming that the samples are "monolithed" in a file called "Factory Sound Data"? It's the only file in the install that looks big enough to contain samples...
