I'm sorry you're running into this issue. I think it's trying to download and install the following Microsoft Library Installer:
Could you try manually downloading that, and then run it? Hopefully you'll be able to directly download it and run, which will hopefully make the installer happy. After you do that, run the ProSeries installer.
Alternatively.. if you get the CD it's supposed to load that file direct from the CD.
