Windows Terminal version

1.21.2701

Windows build number

10.0.20348.2762 (Windows Server 2022 Standard)

Other Software

N/A

Steps to reproduce

  1. Downloaded the latest Stable release (1.21.2701) as a .msixbundle.
  2. Copied the installer to my offline Windows Server 2022 machine
  3. Tried to follow the "Other install methods" on https://github.com/microsoft/terminal, specially:
  4. Double-clicking the .msixbundle file didn't work, as there was no handler for this file type. Ok, disappointing, but I'll use PowerShell instead.
  5. Ran Add-AppxPackage in Powershell

Expected Behavior

Bundle should install correctly, including dependencies, without requiring additional downloads .

Actual Behavior

Add-AppxPackage fails with the following error:

Deployment failed with HRESULT: 0x80073CF3, Package failed updates, dependency, or conflict validation. Windows cannot install package Microsoft.WindowsTerminal_1.21.2701.0.x64 because this package depends on a framework that could not be found. Provide the framework Microsoft.UI.Xaml.2.8 publiched by [... etc].
