UniGetUI Version

2026.1.8

Windows version, edition, and architecture

Windows 11 Pro

Describe your issue

Since 2026.1.8 when bundled WinGet was removed, I can no longer update WinGet packages. This is because Avalonia is looking for C:\Program Files\UniGetUI\Avalonia\Assets\Utilities\UniGetUI Elevator.exe which does not exist. UniGetUI Elevator.exe exists in C:\Program Files\UniGetUI\Assets\Utilities.

Tested in Classic UI mode and WinGet works as expected.

Steps to reproduce the issue

Try to update a package which needs UniGetUI Elevator.exe.
