All, My new Beelink SER5 PRO Mini PC,AMD Ryzen 7 5800H Mini PC ( SER5 PRO-E-16500EJOW64PRO-DP/XB ) was delivered today and Windows will not activate. “We can’t activate Windows on this device because the product key was already used on another device. If you think it wasn’t used on another device, select Troubleshoot below. Error code: 0xC004C020”. I select “Troubleshoot” and it doesn’t fix the problem. The last 5 characters displayed for the current Product key are “B4G6Y”. Please let me know how to properly contact support so that I can get this problem resolved. - Terry

Here’s my product info and serial number if needed… 9Υ.2890830A20 Product:MINI PC SN:Y58004JF20792 SER5 PRO-E-16500EJOW64PRO-DP/XB Thanks, Terry

Terry Cunningham Hi there, Could you please troubleshoot and repair it again after 8 hours? If it doesn’t work either, we will send you a key.

Thank you for the reply. I tried troubleshoot again but Windows will still not activate on this Mini PC. What information do I need to provide to receive a replacement Windows 11 Pro product key? -Terry

Can Beelink support please respond and assist me with receiving a replacement Windows 11 Pro license key? Activation and troubleshooting are not working. My alternative is to send the computer back to Amazon for a refund, and I’m going to have to do that very soon if I can’t get the Operating System properly activated. -Terry

Here’s the activation screen and Troubleshooting popup for my SER5 PRO Mini PC…

Here is my serial number label.
