It looks like you might have some virus protection or local policy preventing us from writing to the tmp dir. We need to write a dll there in order to perform some actions and it is being prevented from finding it. I would check with your IT to remove these restrictions.
System.DllNotFoundException: Unable to load DLL 'C:\Users\79703\AppData\Local\Temp\tmpAF15.tmp': Zugriff verweigert (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
