#DECRYPT NEXTAB NX1610132S PS UPGRADE#
upgrade your PowerShell version to 3 - 5x.Īnother cross-compatible solution for AES file encryption using I have no PowerShellv2 anywhere in my environment to saintly check though.
Get-Command -Name Export-moduleMemberĬmdlet Export-ModuleMember 3.0.0.0
So, the fact that it is failing, should be expected, because if memory serves, Export-ModuleMember was not introduced until PowerShellv3.
