[scribus] scribus-1.3.5svn-090701-rc3.exe does not find ghostscript on Vista 64

[Ted Shapin]

How can I make scribus locate Ghostscript?

I am running Vista 64 SP1

I installed gs864w64.exe and gsv49w64.exe
Ghostscript works fine. I can view pdf files.
I installed scirbu-1.3.5svn-090701-rc3.exe

But SCRIBUS gives an error msg on starting: "Ghostscript: You cannot
used EPS images or PS print Preview"

Help please. Thanks!
