I'm using Windows Vista, I dowloaded the program from the website. It says dowload complete and gives you the click to open AutoCad link, when I click on this it asks what program I want to use to open the file (which is named with just a bunch of letters and numbers). Any program I try to use won't work and it won't let me download AutoCAD again. Any help...
Add an .exe extension to the end of your filename and try to launch it.
