Request for Intel SGX Platform Software (PSW) Installer for Windows

ahsan08 — Wed, 14 May 2025 20:13:15 GMT

Hi Intel Support,

I’m looking to enable Intel® SGX on a system to support UHD Blu-ray playback with PowerDVD.
BIOS SGX is enabled and the driver is present, but I need the original Intel SGX PSW for Windows installer (e.g. v2.17.1.1 or v2.25.100.3) to correctly set up the AESM service and runtime environment.

The NuGet SDK version does not include these runtime components.

Could you please provide a link to the most recent .exe or .msi Windows installer?

Thank you for your consideration and cooperation.

Best Regards,

Ahsan.

Hello Ahsan.

If you have SGX properly enabled in the BIOS and also have Windows Update enabled, all components should automatically be downloaded and installed alongside the SGX driver.

But, you can also get the latest version at the link below:

Hi,

I did download the files but it doesn't have the .msi or .exe file that I can run to install. Can you please let me know the instructions if I am missing on anything. As you can see below the base folder has this.

this is what the chatgpt is saying as I am getting help from that too.. I hope you can help me with the instructions.

This DCAP package does not replace the Intel SGX PSW (Platform Software) for consumer systems. PowerDVD, for instance, will not recognize this as an SGX runtime unless the proper PSW (with AESM service installer) is installed via .exe or .msi.

Unfortunately, due to Intel’s deprecation of SGX for consumers, that proper PSW installer (sgx_psw_2.x.x.x.exe) is no longer available from Intel's official site. If you want to proceed, I can:

Help script a workaround using the extracted files
Or help you file a request to Intel support directly

Hello again.

Please see the Install Guide included in the "documents" folder inside that .zip file... there you will see the command below to manually install the PSW:

pnputil /add-driver sgx_psw.inf /install

Regards.

If you go to "Device Manager" on your system, and expand "System Devices", do you see either "Intel(R) Software Guard Extensions Device" or "SGX Device"?

If you do not, that means SGX is not enabled in your BIOS. You'll need to enable SGX in your BIOS.

Hi,

I see in my Device Manager that I have SGX, please see below screen shot.

Please advise.

Thanks for the screenshot. It indicates SGX is enabled in the BIOS.

I'm surprised to see two of the "Intel(R) Software Guard Extensions Device" listed though. Some questions:

1) What CPU do you have?

I was surprised to see Xeon in your devices, and wanted to be sure.

2) In "Device Manager", instead of "System Devices", if you look under "Software Components", is there an "Intel(R) Software Guard Extensions Software" listed?

If so, can you right click on it and see its properties to see what version is installed?

3) Using command prompt (cmd, not powershell), you can determine if the AESM has been installed and its state by executing these "sc" commands:

CMD> sc qc aesmservice
CMD> sc query aesmservice

Thanks,

Francisco

Hi,

This is the cpu I have

Intel® Core™ i7-10700K

10th Gen (Comet Lake)
8 cores / 16 threads
Base: 3.8 GHz, Turbo: up to 5.1 GHz

Under the software components I do see SGX

this is the version number

Here is the first SC command output

Here is 2nd SC command output

Please advise.

It appears the latest version of the drivers are installed, but AESM service failed to start with an unspecified error.

Do you get more info if you execute

CMD> sc start aesmservice

If that output gives you an obvious next step, you can go ahead and try it. You may also get more info about why the AESM failed to start up from "Event Viewer" -> “Applications and Services Logs”

AESMService

SGX/Admin

SGX/Diagnostic

Knowing why AESM failed may help.

If we can't get a good enough read on why it failed, you will probably end up having to uninstall+reinstall the devices to try and fix this issue. This is a system change, and uninstalling devices/drivers can always impact the stability of your system, but if that is something you are willing to try then,

You should be able to uninstall by first selecting the

"Software Components" -> "Intel(R) Software Guard Extensions Software" -> (right click) "Uninstall device"

then both instances of:

"System Devices" -> "Intel(R) Software Guard Extensions Device" -> (right click) "Uninstall device"

Uninstalling the System Device will require a reboot. I would opt to not reboot until you've uninstalled both instances (I'm still not sure why you have 2 instances).

After the reboot, the drivers will reinstall for those devices and the devices should reappear in Device Manager.

I don't know how comfortable you are with "uninstalling devices" from device manager, but you can try the first half of this post for the diagnostics steps first if you like.

Thanks,

Francisco
