If I ever start a software company, I’m going to have CD images of all of our products online. (Or just allow someone to download a little app that will install the whole thing over the Web.) You’ll have to enter your license key to get them, of course.
I’m trying to install a big application. I’m missing one of four disks, and thus can’t do it. I downloaded it from the web, actually (hey, it’s legal!), but it appears to be a cracked version, and thus the “legitimate” installer doesn’t recognize it as the right CD.
