gs850w32.exe

Nope, went to the link. No ...32c.exe there either. It appears that the Scribus folks don't want windows users. I wish they'd just said that rather than listing a non-existant required program. I presume it is some sort of anti-Windows user joke.

gs850w32.exe is a compressed file. Download it and run it and it will create a directory called gs8.50.

Inside that is a directory called bin.

Inside that is gswin32c.exe

It's not the Scribus' folks problem that Windows has an archaic way of installing software.
