We no longer support Windows 7 but have previously identified a known issue that affects these machines running older versions of PowerShell. The latest AutoElevate agent relies on a function available only in PowerShell 5.0 and above. To determine the PowerShell version on your problematic machines, please follow these steps:

Open PowerShell.

Run the following command: 

(Get-Host).Version

If the reported PowerShell version is 2.0, resolving the issue involves upgrading the Windows Management Framework (WMF) to at least version 3. 

You can find detailed instructions and download links for upgrading PowerShell in this Microsoft article: Installing Windows PowerShell.

By ensuring that your machines are running a compatible version of PowerShell, you can resolve the issue and improve overall system compatibility.
