Starting in the Insider Preview build 25905.1000 in the Canary Channel, we have removed support for Arm32 UWP applications from Windows on Arm, as documented here:
Windows 11 Specs and System Requirements. After the OS upgrade, any installed Arm32 applications will no longer launch on your device. Note that this does not affect Arm64 applications.
- During setup, you will see a message with a list of applications that are currently Arm32 installed on the system.
- In many cases, the list of impacted applications will be reduced by manually forcing the Microsoft Store to install any pending application updates prior to the OS upgrade. To do this, launch the Microsoft Store application, choose “library”, then click on the “Get Updates” button.
- After the OS upgrade is complete, to fix any Arm32 applications, you will need to manually uninstall then reinstall those applications from the Microsoft Store. By doing so, you will install a compatible version that will run on your device.
