Hello, My Windows Pro upgrade product key for XP doesn't work. I have used it once on an old computer but I'm getting rid of that one and using a different one that I want to upgrade. Is that the problem? If so, can I fix it?

First, you must have a CD that is the same type on install as the product key; full, upgrade, OEM, retail, volume licensing, etc.
Then, you must use the CD correctly. An OEM CD will only allow a full install or repair, not an upgrade.
This is an original MS CD. I called MS & because we used it on our old computer we can't use it on the one we are using now. They will give us a new product key if we we pay $99 for tech support. I declined. Thanks anyway!
