ohh found the issue... was running in the latest PowerShell Core 7.3.4, when switching to legacy v5.0 then it works!

Hi @pbering,

Great to see you fixed your issue. However, probably the issue was not related to PS, because we support PS7.

Thanks,

Hi Francisco,

I think this issue should remain open. The issue is in "C:\Program Files\WindowsPowerShell\Modules\AksEdge\1.1.220.0\AksEdge.psm1" line 4779, if you run the following in PowerShell 7.3.4:

& "C:\Program Files\AksEdge\AksEdgeWindows-v1.exe" "x" "-o""C:\temp""" "-y" 

it fails with The filename, directory name, or volume label syntax is incorrect.. But if you run it in PowerShell 5 then it works and extracts fine.

If the quoting of the -o argment is removed so the line looks becomes:

& "C:\Program Files\AksEdge\AksEdgeWindows-v1.exe" "x" -o""C:\temp"" "-y" 

The it works across v5 and v7.

Hi @pbering,

Closing this issue - It was fixed with 1.2.414.0 release.
