I am trying to map a drive in PowerShell 2.0 and getting this error?
New-PSDrive –Name ftp –PSProvider FileSystem –Root “\\\\server\\folder” -Credential $cre
If you still get the error after installing KB2819745 (powershell 4) then you might have forgotten Dotnet 4.5.
DotNet 4.5 is a requirement for WinRM 4 / Powershell 4, yet the msu installs without it.
This was the issue i was facing, after installing KB2819745 i still got the error. Install Dotnet 4.5 and then rerun KB2819745. Strangely it will reinstall when you installed dotnet, but without dotnet it says its already installed
