You can find it in the root directory of your original installation media.

Thanks Vlad, but I don't have anymore the disk ( stolen with my laptop), and in the copy of the program files in my Hard disk the acad.msi file is bad or corrupted, because doesn't work for the unistall issue.I can't find it in any place in the net, and I just need it for to unistall and try to reinstall form the disk copy (image) from the hard disk.is there any archive I can visit and download it?thanks

You can ask your dealer for the replacement media or a trial version.
