scripts/verify-windows.ps1 does not find python3 that has been installed by Windows itself. The script reports the error

C:\njs\Azure-Kinect-Sensor-SDK\scripts\verify-windows.ps1 : Unable to find python 3. Please install python3 and add it
to your path
At line:1 char:1
+ .\verify-windows.ps1
+ ~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,verify-windows.ps1

Setup

Repro

  1. Run scripts/verify-windows.ps1

Result

C:\njs\Azure-Kinect-Sensor-SDK\scripts\verify-windows.ps1 : Unable to find python 3. Please install python3 and add it
to your path
At line:1 char:1
+ .\verify-windows.ps1
+ ~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,verify-windows.ps1

Expected

No error and the successful output "Machine setup. Please use Visual Studio Developer Command prompt to build."

Notes

If I run the command of line 86 of the verify script Get-Command -All -Name "python" I get the result

PS C:\njs\Azure-Kinect-Sensor-SDK\scripts> Get-Command -All -Name "python"

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Application     python.exe                                         0.0.0.0    C:\Users\dale\AppData\Local\Microsoft\WindowsApps\python.exe

and if at that same ps prompt I type that long path, or python, or python3...then all three methods run python 3...

Python 3.8.9 (tags/v3.8.9:a743f81, Apr  2 2021, 11:10:41) [MSC v.1928 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

This suggests that the verify script's method of version checking is not sufficient to detect Windows Store installed python. Naturally, the Windows Store is....desired to also be supported. This is likely related to the Windows Store and App Execution Aliases.

It is not possible to add the Windows Store python manually to the PATH. That location is typically cryptic and not user maintainable. For example, on my computer it is C:\Users\dale\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0

My fix (which you are welcome to copy) is to update verify-windows.ps1 as follows

line 85 change from

if (-not (Get-Command -All -Name "python" | Where-Object { $_.Version -ge [Version]"3.0" }))

to

if (-not (Get-Command -All -Name "python3"))

Using python3 is a reliable method to check if python v3.x is installed and available on the path, and it works across all platforms, install types, app execution aliases, shortcuts, etc.
