Cannot load Microsoft.SharePoint.Client.dll in powershell script

im trying to connect to an offce365 sharepoint site using a powershell script. However, none of commands I've tried to load the sharepoint assemblies are working.

The error message (sorry, it's German) looks like this:

Add-Type : Die Datei oder Assembly "file:///'C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll" oder eine Abhängigkeit davon wurde nicht gefunden. Die Assembly wird von einer Laufzeit erstellt, die aktueller als die derzeit geladene Laufzeit ist, und kann nicht geladen werden.
Bei C:\Users\****\Desktop\onfb\odfb.ps1:6 Zeichen:9
+ Add-Type <<<<  -Path 'C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll'
    + CategoryInfo          : NotSpecified: (:) [Add-Type], BadImageFormatException
    + FullyQualifiedErrorId : System.BadImageFormatException,Microsoft.PowerShell.Commands.AddTypeCommand

It says, the the component (or a dependency) could either not be found, or it is created by a newer version than the one I'm using.

First I tried loading the inital files with 

Add-Type -Path 'C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll'

After that I tried the following command:

Add-Type -Path ([System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client").location)

I also tried copying the files to another folder, and changed the reference accordingly.

I also set the 

<runtime>
    <loadfromremotesources enabled="true"/>
</runtime>

in the powershell.exe.config file. Which wasn't there, so I created it.

I'm running the powershell in elevated mode and also tried with an unrestricted security.

Does anyone know how to solve this?

Thanks!

What worked for me was to install the latest SharePoint Online Client Components SDK. Then, the libraries could be loaded without errors.

The precise error message in English would be:

This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

Most likely it occurs since you are using PowerShell version 2 but SharePoint Online Client Components SDK is targeting .Net Framework v4.0 enter image description here

How to determine installed PowerShell version:

PS C:\> $PSVersionTable.PSVersion

The .NET 4 CLR can load .NET 2 assemblies , but not vice versa. So, you have to upgrade PowerShell.
