Activate with the Product Key on the COA sticker - at the link at the bottom of Computer>Properties page.

Did you wipe the HD as suggested from start?

Did you try what I suggested? It often gets rid of that error no matter how it's caused or shouldn't be caused.

Your Product Key is listed on the COA sticker. Click Change Key link at Computer>Properties to insert it. You may need to make the robocall to sort the batch key on sticker. If the link is not there, google slmgr commands to see how to insert key via Command line.

Otherwise call your manufacturer's tech support to get it activated.
