You'll need to have a legitimate license key to install them, but hard to find install media for Microsoft products, particularly those they may be a version or two past their prime, can be located through the download tool here at heidoc.net.
Now I'll admit I was pretty skeptical about this, but searching on the reputation and safety of heidoc.net raised no red flags, and their tool actually generates download links on the microsoft.com website. I even went so far as to cut and paste the link and manually re-type the Microsoft domain address to be certain that there were no character set tricks making a non-microsoft site look like a Microsoft site.
Given that the downloads are coming from Microsoft, I'm calling them legit. Remember, if you don't have a legit license key to install them, these downloads give you nothing but bandwidth consumption.
