This installer option currently sets the destination for the documents that are referenced by the shortcuts. I'm am not sure why anyone would put those documents somewhere-else. Here, the shortcuts themselves are always placed in:
...\Start Menu\Programs\TX16Wx Software Sampler (x86)
I believe that it should let us select the folder into which the shortcuts will be placed; e.g.
...\Start Menu\Programs\Music\CWI Tec\TX16Wx\
That way I can organise my Program Shortcuts that way I want them to be.
