Using Server 2012 R2 Essentials with a Fuji slic 2.3 in the bios, certificate & self generated key it activated fine with no problems. But looking in the event log every few minutes I'm getting ... SERVER1058WarningMicrosoft-Windows-Security-SPP Application Installation of the Proof of Purchase from the ACPI table failed. Error code: 0xC004F057 It's not entirely happy It seems to be looking for the (non existent) firmware key corresponding to the one I've entered. 0xC004F057 is fatal on Win7 and maybe in the future more serious for 2012 R2. Has anyone been getting these events or am I just unlucky on the key I generated?
