You can only use those parts of Alnuth that do not rely on the interface.
There will be a new version of Alnuth interfacing to Pari/GP instead of KANT/KASH, but retaining the same functionality on the GAP side. This new version of Alnuth will work under Windows, but only with GAP 4.5. (You might have seen the announcement of the second beta version, GAP 4.5.2, yesterday.) So, if you are in a hurry to use Alnuth under Windows you could try GAP 4.5.2 and I can send you a preliminary version of the new Alnuth in a separate email (attachments are stripped from GAP Forum emails). > 1.
