Unable to re-activate license for an AWS marketplace machine
- Apr 05, 2016
The 12.0-HF1 AMIs for Hourly Billing are not currently available in the marketplace.
So this sounds like you are trying to install the 12.0-HF1 .iso (for BYOL) into slot 1.2 and then booting to that volume.
If you did apply a BYOL license to a HB instance, AWS 'may' still see it as a Hourly billing instance (from the original ami-id) and will bill you as if it was. So the process is:
"To convert an HB license to a BYOL license, you launch a new BYOL instance, apply the BYOL license, and move the configuration."
Since you are using Hourly Billing, you will have to wait for the new 12.0-HF1 HB instances to be made available. When the new AMIs are available the upgrade process between Hourly Billing instances it to:
"To update an HB license you launch a new instance, apply the existing configuration, and retire the old HB instance."
