Try this:

  (push '("\\.djvu$" . "\"C:\\New Folder\\WinDjView-0.5.exe\" %s") 
extview-application-associations)

Explanation: The command that is the cdr of the association is passed
to the Windows API that invokes programs.  As you probably well know,
file names that include embedded blanks need to be quoted to signal
the OS that this whitespace does not end the file name.
