You'd have to go out and buy a copy of 32-bit Windows and reinstall the OS, wiping everything you have on there right now. Either that or you can go out and purchase a 64-bit version of Autocad.
You dont need to change it you only need to find a way to support your 32 bit applications for windows 7. this is a link on how to make it work =%26gt; http://www.techsupportalert.com/content/
you cant change like that, it is configured by hardware, you will have to find a 64bit version of the software
