Error using Powershell inside a Workflow

Question

Hello,
I have the following scenario: I want to change the Status of every Incident that is created to "Neu". This is a custom Status we created. So my first tought was to use the Authoring Tool with a Workflow. I created a Workflow wich will trigger
whenever a Incident is created (simple) and then I used the Windows PowerShell Script Activity, with the following code:
My First Question Is, I need the ID of the Incident, so I create a new Script Property and as a Value I select
Use a class property -> Incident -> ID, is this way correct?
Then I insert this value in my Code via $id = "$IncidentID";, there is also my question is that correct?
I have tested the Code, it works. If I insert a Incident ID manually it changes the status.
So after I created the Workflow, I saved the MP and copied the .dll to my SM Folder and importet my MP. But if create a new Incident the Status is "Active" and it says the Workflow failed. I looked into the log and found an Error Message, after
some research I found a solution that said I had to modify my MonitoringHost.exe.config
(the error Message had something to with a PowerShell Module/Assembly missing) so I added the follwoing lines:
<dependentAssembly>
<assemblyIdentity name="Microsoft.EnterpriseManagement.Moduls.PowerShell" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="6.0.4900.0" newVersion="7.0.5000.0" />
But now I get the following Message:
Can somebody help me?
