Cause

This issue is caused when NewtonSoft.Json.dll, was not properly registered when PowerCLI was installed.
or when another version of the library was already installed on the local system and PowerCLI failed to update it during its own installation, because it was in use by another application.

Resolution

To resolve this issue, NewtonSoft.Json.dll should be register to the Global Assembly Cache of the Windows-System by running the following commands in PowerShell:

# [System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")
# $publish = New-Object System.EnterpriseServices.Internal.Publish
# $publish.GacInstall("C:\Program Files\WindowsPowerShell\Modules\VMware.VimAutomation.Common\12.0.0.15939652\net45\Newtonsoft.Json.dll ")
