Add-Type in PowerShell not working

2016-09-30 14:31

I have installed WinSCP v.5.7.7. in C:\Program Files (x86)\WinSCP\ and unlocked the WinSCPnet.dll as documented, but when I enter Add-Type -Path "WinSCPnet.dll" in PowerShell it still fails:

 Add-Type : Could not load file or assembly 'file:///C:\Windows\system32\WinSCPnet.dll' or one of its 
 dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) 
 At line:1 char:1 
 + Add-Type -Path "WinSCPnet.dll" 
 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
 + CategoryInfo : NotSpecified: (:) [Add-Type], FileLoadException 
 + FullyQualifiedErrorId : System.IO.FileLoadException,Microsoft.PowerShell.Commands.AddTypeComma 
 nd

This is a new Windows 2012R2 server. I need this to work as I have to convert all of my VBS scripts that call WinSCP to PowerShell scripts ASAP.

Why are you loading the assembly from C:\Windows\system32\WinSCPnet.dll?

Show us your code!

I found the correct syntax:

Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

Add_Tyoe not working

I unblocked the DLL and this is what I get when I attempt to run the PS1 script:

Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"
$sessionOptions = New-Object -ComObject WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "myserver"
    UserName = "myuser"
    Password = "mypassword"
    SshHostKeyFingerprint = "ssh-rsa 2048 fc:44:00:23:f2:8a:aa:00:64:f2:d8:36:4c:2e:6d:f1"
}

New-Object : Retrieving the COM class factory for component with CLSID {2D4EF368-EE80-4C15-AE77-D12AEAF4B00A} failed due to the following error: 
80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Why do you instantiate the class via COM? The WinSCP .NET assembly is a native .NET assembly (as the name says). Instantiate the class directly, as all the examples show:

Or have the WinSCP GUI generate a code template for you:

Loading the DLL like below worked for me

Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

@anudeep574: Rather use a copy of the assembly dedicated for the script.
See https://winscp.net/eng/docs/library_powershell#install

Powershell in Administrator mode

I had a similar issue, then realised it was down to running PowerShell as an Administrator.
