i installed the acad 2006 onto my newer laptop which has the windows xp version. once the installation was completed i opened the program and than a window poped up saying this version of windows doesnt support acad 2006. than it told me to go to their website and dowload their upgrades to make it work so i downloaded a bunch of upgrades and still it doesnt work. is there some type of program or other upgrade out there that will get it to work???? thank you
