Hello,

Thank you for the work and time you've put into this script!

This is probably an easy question for you.

What dependency am I missing if I get the following error on one of my 2008 R2 machines?

Add-Type : The file or assembly "System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad3
64e35" or a dependency could not be found. The system can't find the file.
Bei C:\Scripte\DeployCryptoBlocker.ps1:13 Zeichen:13

This function is used in the ConvertFrom-JSON20 function.

Thank you very much in advance!

I believe this is due to not having a new enough version of PowerShell. Please upgrade to at least v4 (v5.1 is the latest at the time of writing) and that should fix your problem.

Could the script check for Powershell version, and exit gracefully if it's not sufficient?

You're missing .NET 3.5.x feature installed on your server, at least this worked for me.

I think it is the missing .Net 3.5 indeed. Thank you all!
