Windows 10: Windows 10 – Intel SGX AESM Platform Services initialization fails due to DAL error on XPS...

When I run the “CyberLink Ultra HD Blu-ray Advisor” vs. 2.0.3201.0 I receive error # 21205: “The required Intel SGX … wasn’t started.” This renders Ultra HD Blu-ray discs unplayable.


I have a Dell XPS 15 9570 2018 notebook computer with a 59 Hz UHD IPS @ 3840 x 2160 monitor, BIOS 1.15.0 dated 25Dec2019, released 14Jan2020, 32GB DDR4.

The CPU is an 8th gen. Intel Core i7 8750H @ 2.20+ GHz, Coffee Lake chipset, Intel UHD Graphics 630 [driver vs. 25.20.100.7262].

The machine is also equipped with an Nvidia GeForce GTX 1050 Ti with Max-Q board, but Intel is the default GPU.

OS: Windows 10 10.0.18362.628 18362.19h1_release.190318-1202

[I gather that this = the May 2019 Update, “Version 1903”]


Intel SGX is enabled in the BIOS and set to allocate 128 MBI notice in the Task Manager that the Intel SGX Application Enclave Services Manager is using between 0.3 MB & 2.5 MB depending on when I look. [No running process has allocated to itself 128 MB of RAM although arguably SGX RAM isn’t listed here.]


The Windows Device Manager, under “System devices” lists the 'Intel Software Guard Extensions Device' driver 2.5.100.2 dated 9/19/2019 – there are no flags; the device is working properly.


Prior to an Intel driver update, the “Intel SGX Application Enclave Service AESM” was shown to be running.

Currently, the “Intel SGX AESM” service is listed as running.

According to the Event Viewer’s SGX/Diagnostic informational entries, the AESM Service PSW vs. is 2.5.101.3 this is Intel’s latest release, dated 11/22/2019.


SERVICE STATUS – On this notebook, it occurred exactly ONCE out of 1,758 events in the Event Viewer, SGX/Admin event log that a “Critical” error happened describedas “AESMService: SGX is Disabled at AESM Service startup”. Since this only happened once, I don’t see it as highly significant.

However, there are frequent “Warning”s to the effect that “AESMService: Platform Services initialization failed due to DAL error”. {DAL = Dynamic Application Loaderthe DAL HIS is installed by the Intel Management Engine installer}Mostlog entries say, “AESMService: Platform Services initializing”OR “AESM Service started”. Unfortunately, it appears to be the case that the most recent entryin the event list istypically an initialization failure warning …so I seem to be perpetually in a non-operative state, even though the service is listed as running,


ACTIONS – I went to the BIOS and disabled SGX, restarted, tested, went back to the BIOS, re-enabled SGX, retested, all to no avail.


I keep my system updated and nothing appears to be amiss with the Intel Management Engine. Nevertheless, I downloaded and did a repair installation of Dell’s package “Intel Management Engine Components Installer” vs. 1932.12.0.1298 A04 dated 9Aug19. The “CyberLink Ultra HD Blu-ray Advisor” still fails with error # 21205 and I still get“AESMService: Platform Services initialization failed due to DAL error”events.


As this point, I am aware of no additional steps I can take. I would have expected that by 2018 issues with Intel SGX and DAL HIS would have been sorted.

I notice from the forum that when Windows 10 build 17083 was released, suddenly SGX was no longer operable for many users. Naturally, I wonder if my problem is a Windows issue as well.


I purchased this painfully top-dollar Microsoft-based Ultra HD notebook with every expectation that I would be able to play Ultra HD video on it, but I am stymied.


What should I do now?

SGX  AESM Service

Hi ,

I wish to create a SGX platform in windows and now I install all app of the SGX.



But when I install done, it says "Intel(R) SGX is currently disabled.

Contact your computer manufacturer to see if SGX is supported on your platform."

while CLICK the "SgxPlatformCapabilityTool" .



I check the computer event to make sure what happen is .



It says "AESMService: SGX is Disabled at AESM Service startup "



I find all the way from Google but I can't find out



Has anyone done this with or without issues?



Thanks a lot .

SGX Service unavailable

Hi,

After trying to re enable one by one services launched at startup, I realized that none of those is causing the error except one:

Intel SGX AESM

When this service is stopped the critical error does not show up in the event viewer, when this service is activated at startup the error shows up every 5 minutes.

As long as the error is labeled "AESM Service: SGX Service unavailable" I conclude that if AESM Service is not started it does not report the SGX Service unavailable error but if it is started I still wonder what is causing it to report this error every
5 minutes.

Any other suggestion o find out?
