Installing Windows Terminal .msixbundle using PowerShell Add-AppxPackage

I'm trying to install Windows Terminal on Windows 10 v1803 [build 17134.13.04] where I don't have any admin privileges and Microsoft Store has also been deactivated. I downloaded the .msixbundle from the GitHub release page and used the command from here:

add-appxpackage -Path ".\Microsoft.WindowsTerminal_1.4.3141.0_8wekyb3d8bbwe.msixbundle"

However, I recieve error:

add-appxpackage : Deployment failed with HRESULT: 0x80073CF0, Package could not be opened.
error 0x8007007B: Opening the package from location Microsoft.WindowsTerminal_1.4.3141.0_8wekyb3d8bbwe.msixbundle
failed.

NOTE: For additional information, look for [ActivityId] b425a102-b6a8-0001-5add-56b4a8b6d601
in the Event Log or use the command line Get-AppxLog -ActivityID b425a102-b6a8-0001-5add-56b4a8b6d601

What is the problem and how I can resolve it?

The reason you're probably getting that error is because Window Terminal requires Windows 10 v1903 or later.

Windows Terminal requires Windows 10 1903 (build 18362) or later
