PsfLauncher64.exe - The system cannot find the file specified

[Pollewops]

Created a case at Microsoft and got the feedback that I need to create a GitHub incident for it. So here I create an incident alhough the issue is already raised 6 months ago !!!!!

Issue:
PsfLauncher does not work since it can't find the powershell.exe. This is due to the missing [HKEY_LOCAL_MACHINE\Software\Microsoft\PowerShell\1] Installed = 1 registry value.

Why is that value not there:
Due to the fact PowerShell 2.0 is not supported anymore by Microsoft for some years, our company starts uninstalling PowerShell 2.0 from the devices and by that the registry value is also removed from the systems. The result is that MSIX MS PSF does not work anymore :-(

Resolution:
Please update MS PSF so it supports the [HKEY_LOCAL_MACHINE\Software\Microsoft\PowerShell\3] Installed = 1 registry value also when the PowerShell\1 is not available.
The Tim Mangan fork already had this fix for very long time, so why the MS PSF not??

Why not use the Tim Mangan fork:
When using the Tim Mangan fork PSF, we do not get support from Microsoft when we create a case for a MSIX packaging issue. So that why we prefer to use the Microsoft PSF, but then it should work at least.

To make this worse Microsoft is now actively removing Powershell 2.0 this month without fixing PSF. So this morning our packages started to error after users updated.

Yes only way forward is to use the Tim Mangan fork PSF.
I even had cases with Microsoft in which they (MS) also suggested to use that fork.
