If you are not running in S mode, it is probably being blocked by smart app control. It is up to the app developer to have a valid signature to pass smart app control. There should be some error message if that is the case.

You can turn this feature off and attempt to install the app. However, know at AT THIS TIME, you can not turn the feature back on without a clean install. However, this requirement to re-enable it is being addressed in current insider versions of Windows so will soon change..
I have had Smart App Control disabled since the beginning.
You can find this setting by typing "smart app" in windows search.

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

    UPDATE - 11 April 2026: due to mechanical deterioration this PC has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

    I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.
