Intel XTU signature validation failed. I9 14900k

[Roots]

I've had a issue for close to 6 or 7 months where Intel XTU refuses to work on my computer. I've tried what feels like everything to try and get it to work but I haven't been successful. Here's the issue I'm encountering:

"Permission Denied: XTU signature validation failed. One or more files does not have a valid signature!"

Things I have done so far:

1. Stopped the services.
2. Compeletly uninstalled XTU (using Intel intructions), deleted all files related to XTU (again using Intel intructions) and wiped the registry for XTU, then rebooted. (Multiple times...)

3. Checked previous posts with the same issue which stated to do the above ^.

4. Verified certificates are up to date.

5. Used certutil to verify the integrity of the installer.

6. Updated to the latest BIOS for my motherboard as well as the latest ME update.

Not really sure where to go from here. The program worked fine before, however, I RMA'd my 14900k awhile back and received a new one that is currently in my computer. After replacing the previous 14900k, the program no longer works. No other hardware changes were made other than the CPU. I've attached the log(s) that is generated by XTU. Any help would be greatly appreciated.

Attached here is the verbose version of the XTU log file as well as my SSU log file as I figured this would also be asked for.

Hi Roots,

Thank you for reaching out on the Intel Community Forum. May I recommend trying the following troubleshooting steps?'

• Reboot your system and rerun the Intel® XTU installer.
• Uninstall Intel® XTU by following the How to Uninstall the Intel® Extreme Tuning Utility (Intel® XTU) article.
• Download and install the latest version of Intel® XTU.
• Make sure you have the latest BIOS version installed. You may want to contact the board manufacturer to ensure this.
• Admin permission required for this step: manually delete the c:\program files\Intel\Intel(R) Extreme Tuning Utility directory. Be very careful not to delete any other program folders by default.
• If issue persists, update Windows or try a fresh Windows installation.

Once you’ve completed the steps, please let us know the outcome.

If you have any further questions, feel free to reach out. Thank you.

Best regards,

I have accomplished all of these steps already and nothing has changed. I think I've narrowed it down to one driver that ships with the XTU installer: Microsoft.Win32.TaskScheduler.dll. It's the only unsigned driver in any of the XTU folders. When I delete this driver I can progress further into XTU (still doesn't work but it at least looks like it's doing something for XTU). Before XTU can run however, it redownloads this driver which ends up resulting in the same issue.
