Hello Sam Hsu,
Thank you for posting in Q&A forum.
You can try the troubleshooting steps below:
- Ensure the devices can reach the activation servers if using online activation.
- Check the VAMT logs for any errors or issues during the activation process.
- If VAMT encounters issues, you can use the command line for activation:
slmgr.vbs /ipk <your_product_key>
slmgr.vbs /ato
For more detailed guidance, you can refer to the Microsoft documentation on VAMT
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
