Searching around, iText is a Java/C# library you bought/dowloaded right? You probably need to look into how to use C#/.NET assemblies in PowerShell — Viet Than

With the two top answers being use:

[Reflection.Assembly]::LoadFile("c:\temp\tempLib.dll")

or use the built in Cmdlet Add-Type:

Add-Type -Path foo.dll

This looks promising these. I suggest googling specific parts of the error message to figure out if anyone else got a similar problem. My search terms were "The type initializer for 'iText.IO.Util.EncodingUtil' threw an exception. or ~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : TypeInitializationException
