PDFCreator 1.7.3 on Windows 2000?

Trying to install PDFCreator 1.7.3 on Windows 2000, i got error "This program does not support the version of Windows Your computer is running". Where may be problem? On blog I found that v1.3.0 need Windows 2000+, but nothing about that W2k isn't supported yet.
When it's truth, which last PDFCreator version support W2k and is possible to download somewhere?
Thanks, Franta Hanzlik
