Error creating deployment task

Hi there,

Im in the middle of upgrading our master images to Windows 10. Here is what i have done so far:

1. Deployed fresh windows 8.1 image (as that is what our standard has been so far)

2. Updated it to Windows 10 to get new serial out to do a clean install of windows 10. Installed the agent again.

3. Now i want to redeploy a windows 8.1 to use that for a while, but now i get an error message as it seems to not reconize the serials.

See attached picture, showing the error message. Licensing during deployment: Use machine licenses

Any ideas on what to do? 

Best regards,

Allan
