PowerShell v4.0 Add-Type fails

I had this working in PowerShell 2.0 but when I upgraded to v4 it started failing:
Add-Type -Path "WinSCPnet.dll"

This now returns the error:

I noticed that the upgrade to PowerShell v4 also required installing .NET Framework 4.5. I saw another post where you said you can't work with .NET 4.0, so is 4.5 also a problem? If so do you have a workaround?

I do not think we ever said that the assembly does not work with .NET framework 4.0. It does.

Anyway, regarding your error, did you read this?

I ran into this as well.

Aside from the above tip about the dll protection, I had to run the command: "Enable-PSRemoting -Force" . I run in a secure environment so I recommend reading up on that command before using (if so required).

Removing the Windows file attribute that blocks downloaded Internet files did the trick. Thank you very much!
