Descarta2D package for Mathematica 7 is needed

I work with Mathematica 7 and I would like to try the ADD-On “Descarta2D”. A nice but old add-on , not updated after Mathematica 8.
As far as I could find on the web there is a version of Descarta2D that works with Mathematica 7.

I would like to try it. Is there anybody who can help me to find that version ?

Buy a book: Exploring Analytical Geometry with Mathematica 1st Edition.

Yes, I have that book with the CD included. But alas, the version on the CD is not compatibel with Math 7.0.
In later years Descarta2D has been updated to work with Math 7 and Math 8 and I am looking for that version.

Thank you for your answer.
