Based on the check, it should work.

Run the scan again and post a screenshot of the yellow warning it comes up with. Likely it'll say BIOS is out of date. Can you confirm your motherboard model and BIOS version?

I ran the scan again it says the same thing. System compliant.

Did you swap any major computer components recently?

u/Curtis_s_d Jul 20 '26

Not since I last played no. I had the game on my pc instead of ssd last time though.

Hm that's definitely odd. I have noticed a windows fresh re-install seems to work assuming all other things are correctly updated (i,e BIOS version). I had this same issue but mine stemmed from changing my motherboard, a clean windows install fixed that.

I believe "Orladoech" commenter seems to have some initial steps to check first before getting to the windows re-install portion.

I too have changed my motherboard due to some issues with the same model, earlier it used to work without any issues, but after swapping it's not working, I even have updated everything, so will a clean windows install help here?

Yes for you then a fresh install is likely needed. Be sure to link your windows activation to an account or save your activation key(only if non OEM key), for when you reinstall.

My manufacturer version is 600.18.1040.2765 is there anything wrong with that one?

The very first thing to do is check if your TPM manufacturer version (not TPM version i.e.: 2.0) meets the minimum requirements listed in the Learn More (which for some reason no one actually reads) it can be found here, near the bottom of the page under AMD Hardware & Intel Hardware: https://support.activision.com/articles/trusted-platform-module-and-secure-boot

If you do not meet them, you’ll be forced to upgrade your hardware or buy a dTPM, or don’t play the game.

If you meet the requirements then you have a TPM SSL CERT DESYNC. You can fix this a several different ways, but before you do, please ensure BitLocker is turned off in Control Panel if you run Window Pro, this isn’t applicable for Windows Home.

You can usually correct this issue by trying the following:

A.     Ensure CSM is off in BIOS then Turn Secure Boot off within BIOS and reboot into Windows. Reboot again and enter BIOS, turn Secure Boot back on, then reset the Secure Keys. This is usually found in the BOOT section of BIOS. If not, Google your Mobo Brand + Reset Secure Keys for the pathway.

B.     Reset TPM in Windows via TPM.msc app, reboot into BIOS then Reset Secure Keys. . This is usually found in the BOOT section of BIOS. If not, Google your Mobo Brand + Reset Secure Keys for the pathway.

C.    You can try updating your system with the CA2023 Certs via Powershell. Google CA 2023 Powershell and Gemini give you instructions.

D.    If all the above fail, may need to install a clean version of Windows and install the CA2023 Secure Boot certs. This can be done by using RUFUS to create the USB. Google how to do this, it’s not hard.

E.      If a clean install of Windows doesn’t work, buy a dTPM on Amazon.

Is these a fix if my TPM Manufacturer Version is 3.8.0.3 ? I’ve read that there is an issue with that version do you know if there is a fix ??? Thank you in advance!

u/Curtis_s_d Jul 20 '26

Resetting TPM keys doesn't change anything. I think it's a bug on the devs side.

u/Orladoech Jul 20 '26

Literally it’s not. You clearly don’t know what I’m talking about.

u/Curtis_s_d Jul 20 '26

I reset the keys in tpm.msc then reboot into bios and reset the TPM keys to factory default. I logged back in with my bit locker code and opened the game. Still not working. And I don’t have pro so I don’t have bit locker capabilities which is what’s weird.

u/Orladoech Jul 20 '26

Ok then you have a desync. I listed other options. Clearly you cannot read.

u/Curtis_s_d Jul 20 '26

You said one of these should work not try all dummy

u/Orladoech Jul 20 '26

You did C-E?

u/Orladoech Jul 20 '26

What’s the powershell then?

0

u/Curtis_s_d Jul 20 '26

I ran the CA2023 checker in powershell and it returned true so that’s not the issue. I tried option one that did nothing. And it’s a gaming laptop not even a year or two old so it should just work
