Ghostscript for GSView under windows 64 bit arch

I was trying to find forgotten by me information about type reduction for lambda calculus. I went to get Barendregt Lambda Calculi with Types, to find out that it's Postscript version. Because on my fresh box I didn't have GSView I had to download it from a web. By default it tries to find gsdll64.dll in it's path, but a compiled version of a new release of Ghostscript (9.0) is delivered in a plain file form - it does not install anywhere and does not register itself in any path. In order to make it available for GSView one needs to fire up GSView and select Options->Advanced Configure-> in 'Ghostscript DLL' insert a path to the library.
