Yeah same tried everything, i7 12700K.. Guess we have to wait a little bit more

[Dajova]

I use a 12600K and i have the same error. I tried shennry's approach and tried that way and it didnt work at first until i took ownership of the file. THEN i was able to "launch" the app, only for it to greet me with a new error message:  

[MrAgapiGC]

for 12th are on the same train. is not the driver... is intel. maybe down the road

[AhrizinhaSz]

I will be very sad if support for 12 gen takes longer to arrive.

Using a Z790 mobo with 13900K.

Enabled Intel DTT in the bios, Installed the DTT driver, Installed the application through the MS Store, Go to launch and am met with this -

Followed the guide on the 4th page, Uninstalled Intel APO, Rebooted, Then using Driver Store Explorer to wipe the old drivers that were listed, Rebooted, Reinstalled everything, Rebooted, Still doesn't work.

EDIT

Tried also going to the actual exe location and now it opens but if I use the shortcut in the start menu if gives me an error.

@MoKiChU 
I was quite baffled today when I was unable to replicate the results that I had repeatedly seen on the 15th, I removed my posts to not spread incorrect information and was about to issue an apology and was worrying what could possibly have caused such a bad series of false positives, when I remembered I had uninstalled the driver on the 16th and cleared the driverstore cache set to try a newer build when Asus releases them.

The .dv .inf, and .config files from the intel driver subfolders only report as having signatures when the driver has been installed! 

I wish I was joking, this obviously is rather counterintuitive as I would wish to check signatures before installation. 

I'm going to use the driver from Asus as my example as I know it definitely works this way, if you have one of your newer drivers installed you likely would see similar results checking their files but I cannot know for sure without installing them myself.

Download DRV_DTT_Intel_SZ_TSD_W11_64_V101140139039_20231117R from Asus, unzip it somewhere, then with powershell open to the folder containing AsusSetup.exe run my script to use the powershell in-built Get-AuthenticodeSignature to check all files via "ValidateSig.ps1 -s" to check all subfolders.

if you have no DTT driver installed:
In the root folder only AsusSetup.exe will show a valid signature.
In the subfolders .zip, .inf, .catalog and .txt files will all show no signature.
This is how I am sure you expected things to be from your initial response.
(Behaviour may vary if you have a different version of the driver installed to the folder you test as there may be some re-used files, edit - in fact with the 39039 driver installed, testing the 42569 is giving me a mix of results, for example all the .config files validate except for apo.config )

However I assure you that if you uninstall your DTT driver (you probably need to use driverStoreExplorer to remove the store also to prevent any mix up) and then with DTT BIOS Enabled install DRV_DTT_Intel_SZ_TSD_W11_64_V101140139039_20231117R itself, running the script again will find that :
In the root folder only AsusSetup.exe will show a valid signature.
**All** other files in the subfolders will validate except for .zip files and the one license.txt

I hope despite the small hassle you will try this to confirm and you will see that I was not trying to mislead anyone.
I am sorry for the earlier confusion, but this behaviour was obviously very unexpected.

9.0.11405.42569 WHQL installed, and the Intel Application Optimizer working on i9-13900KF here.
Now they're installed, testing all files in the extracted archive's folder reports every file has a valid signature other than Install.cmd and DTT_Intel_Application_Optimization.url, but those two were not expected to be signed.

Thanks, I can confirm that it seems to work:

13th Gen Intel(R) Core(TM) i7-13700K
ASUS TUF GAMING Z790-PLUS WIFI v1641
Drivers TUF GAMING Z790-PLUS WIFIIntel APO app from Windows Store

[UbeRveLT]

Z790 APEX doesn't seem to have BIOS support yet. Can't get it working using any of the methods explained so far.

[ClearedIn2Bravo]

Yes it does, I'm using the Z790 Apex with 14900KS without issue.
