My computor crashed and bought newone with Vista windows. How can i successfully download AutoCAD r 14 onto Vista ?

Download: yes, install and run: no. This is a very unbalanced combination of very old application version and very new OS version.
For Vista, you can use either AutoCAD 2008 or AutoCAD 2007 SP2.

 Thank u for that.I've downloaded AutoCAD R 14 ok. But some items will not work, ie, script ,and some other stuff,but I can draw ok. Can u help please.

I think you will also find many other unneccessary complications - either downgrade your OS or upgrade AutoCAD.

As I am retired now and cant afford those later versions of AutoCAd's I guess I will just have to put up with what I've got, unless I could get one for free but that's very unlikely.Thank u very much for your help.
