    I am on windows 10 19043.985 with my prime x570-Pro. I have AI suite 3.00.79 (dip 3.00.78), no issues what so ever. Sounds like a registry error, but I could be wrong.

    I think it have to do something with the 21H1 update on WIN10

    I dont know if you can uninstall but if you have backup then you can maybe fix it. But i will not change anything. Asus need to fix this asap or make FANEXPERT as standalone software. I use AiSuite only because of FanExpert nothing else

    New AMD Chipset Drivers on AMD Website

    I've got the same issue with AI Suite 3, it's definitely a Win10 update issue.

    Both AI Suite 3 and Armoury Crate do not work.

    I also found 2 posts on the Microsoft website about updates causing AI Suite to crash, they are from 2016 and 2017 so Asus should be aware of previous issues. No solutions were found on either post.

    Just FYI, AMD has newer chipset drivers than what's listed on the Asus driver page. Here's the link. Scroll down and select the options to the chipset on your mobo.

    I finally got it figured out and now they both work.

    I use Macrium Reflect to make a backup image of my C drive so I can restore it later if I need to.

    I restored an image from May 19th when I knew everything was working, and immediately installed StopUpdates10 to keep Windows from downloading and installing any updates.

    I loaded Armoury Crate & it updated. I clicked on Device and updated HAL. Then I updated all the drivers and AI Suite 3.

    When I rebooted, I got 2 errors from AI Suite 3:

    Dipawaymode
    Invalid class string, ProgID: "AsusFanControlService.FanControlManager"

    Aisuite3
    Invalid class string, ProgID: "AsusFanControlService.FanControlManager"

    I uninstalled AI Suite 3 from Programs and Features and rebooted.

    I installed AI Suite 3 again from Armoury Crate and this time I didn't get any errors.

    I checked and made sure both AI Suite 3 and Armoury Crate were working correctly and made a backup image.

    I turned off StopUpdates10 and installed the latest Windows updates and both of them are still working perfectly.

    There seems to be a glitch that Armoury Crate and AI Suite 3 need to be updated first before installing the latest Windows updates.

    I originally installed the Windows updates first, then updated the 2 programs and that's when they both stopped working.
