diff - wscript error

I have just installed Tortoise v 1.2.6.4786

When I try and 'diff' a file that is in conflict, I get the following
message:

Script: C:\Program Files\TortoiseSVN\Diff-Scripts\diff-doc.js
Error: 'Wscript' is undefined
code: 800A1391
Source: Microsoft JScript runtime error

I'm using windows 2000 v 5.0 with service pack 4
and Word 97 SR-2

If anyone can give me an idea of what is happening and how to fix it
that would be great.
