First, Scribus was developed first and foremost on Linux and Unix machines, so sometimes the way things work are not always the 'windows way', but a more OS neutral way. Scribus also is natively ported to MacOSX and the behavior changes are mostly in the way the menus work. Second, a great deal of time and effort has been put into Scribus to generate very high quality commercial grade PDF. Provided you follow the recommended workflow in the documentation, you should have few issues with commercial printing.
For Windows 2000 Only - The GDI+ library from http://www.microsoft.com. Unfortunately, as Scribus is an open source application under the GNU GPL, we cannot include this file within the installer. Windows XP includes this library already.
Windows 2000 SP4 or Windows XP - Windows 98 and ME have not been tested and are not supported. Any and all bug reports relating to Windows 9X will be closed quickly.
256 Mb or more system memory - the more the better. 512Mb or more is strongly recommended for larger more complex documents.
Pentium III or better - 750MHz or better
XP Themes Disabled - Use the "Windows Classic" theme is very strongly recommended. There is a known issue with Custom Themes causing document loading problems. This is especially true with third party themes.
Again, Scribus is very particular about font quality. Use of freeware or shareware fonts is not recommended. There is an extensive and informative set of notes in the online help about fonts and commercial grade printing. Scribus scans fonts on launch and will disable obviously broken or problematic fonts. Those notes are based on experience both with Scribus and commercial printing.
There is a second way to launch Scribus: Console Mode. In the Start > Program Files menu there is a second short cut Scribus -console. This mode merely opens a windows command prompt, but will show line by line, each font and its full path being loaded by Scribus. This will also show any rejected fonts and duplicate fonts Scribus finds, along with other diagnostic info in some cases. Duplicates are not loaded, even if they have different names. One of the font tests Scribus performs on launching is to ensure each font file has a correct Postscript name.
The Scribus Team is pleased to make available the only open source page layout application which runs natively on all 3 major desktop operating systems; Linux, MacOSX and Windows. Both online and direct commercial support is available for Scribus. There is a very friendly community which has developed around Scribus with the active participation of the developers. Enjoy!
