Problem with Intel Application Optimization APO :(

[Davu]

Since I had an old version of XTU1, I had to update to the latest version in order to upload my overclocking result to the Intel website. However, after updating XTU1 (I'm on LGA 1700), I now get the message 'Failed to connect!' I want to point out that all the necessary settings are enabled, because I was using it daily until I had to update XTU1

Hello Davu,

Thank you for posting on Intel Community Forum.

To assist you effectively, kindly provide the information below.

1. Could you confirm whether the issue is with the Extreme Tuning Utility (XTU) or Intel Application Optimization (APO)

2. Kindly attach a screenshot of the error you are seeing

3. What was the last known working XTU version?

Additionally, to have a better understanding of your system configuration and components please generate System Support Utility (SSU) report. Please follow instructions here and send the report - How to get the Intel® System Support Utility Logs on Windows*

I look forward to your response.

So, here’s the situation: XTU works normally. I used to have an older version of XTU—I don’t remember exactly which one—because this SSD was previously installed on an LGA 1151 socket. Back then, I was using XTU and APO without any issues, even with games like FFXIV, which is officially supported.

When I needed to upload my overclocking result to the Intel website, it required that XTU1 be updated to the latest version. So I downloaded the newest version from the official XTU site. But now I’m getting the “Failed to connect!” error, just like in the link that was shared earlier. I’ve already tried uninstalling and reinstalling it from the Microsoft Store, but it still doesn’t work.

Everything used to run perfectly—I never had any problems with APO. While you were replying, I did some research and found out that this is a known issue. Apparently, many users who updated XTU can no longer use APO.

Hello Davu,

Thank you for sharing all this information.

To assist with further investigation, may I kindly request that you share the current version of Intel® Extreme Tuning Utility (XTU) installed on your system? Additionally, please generate and provide the System Support Utility (SSU) report, which will help in reviewing your system configuration in more detail.

Furthermore, could you please confirm whether the error message appears while playing any game, or if it is limited to a specific title only?

Best regards

So, I’m using XTU1 because it’s the version compatible with LGA 1700 — specifically version 7.14.2.45. My system is an AORUS Z790 Pro X WiFi 7 (last bios from july 2025 with new intel microcode) with a 14600K and a 5070 Ti GPU. But ever since I updated XTU, I can’t even open it anymore. I get the error message from the link right before the app launches. I can’t access anything — the message pops up as soon as I double-click to open it.
