If I buy a retail upgrade version, what’s in the box?
You get two DVDs, one 32-bit, one 64-bit. You get a single product key, which you can use to install either version. If you buy the Family Pack, you also get those two DVDs and a single product key, which can be used to activate three PCs in your household.

It’s all about the product key. When you enter the product key, the setup program checks to see whether you installed the product on a clean system that didn’t previously have any version of Windows installed. If the answer is yes, it blocks you from entering that key. Here’s the confusing error message you’ll see:
