That message should also have given a message box with more information, 
saying what the problem was: it does not usually mean the 'shared library' 
named.  It does for me:

'The application failed to start because libfftw3-3.dll was not found.'

Other DLLs are also missing: jpeg62.dll and libtiff3.dll (use pedump to 
find this out).  So you need to use Google to find those DLLs and put them 
on your PATH.

You also need to read 
and suggest to Uwe Ligges what he adds a note about this (it applies to 
SoPhy for libtiff3.dll as well).
