scook
... and the samples may not be in the right place although I am not sure exactly what to look for.

* Scook is correct for this. Whilst it works in Dimension Pro sticking a whole load of .sfz files in the root of the multisamples folder is simply unacceptable. It has been packaged badly.
Also
* The hardgrove collection just copies to the default area and does not honour the folder path for rapture in the registry. You need to move it to the multisamples folder manually afterwards (if it is in a different place).
* Boost 11 which appears to be installed on every update is also hard coded and does not honour the existing file path.
This is a mess that needs fixing.
