In PowerShell you get the following error when trying to import the RoyalDocument.PowerShell.dll:

Import-Module : Could not load file or assembly 'file:///C:\Program Files (x86)\code4ward.net\Royal TS V3\RoyalDocument.PowerShell.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
At line:1 char:14 Import-Module <<<< '.\RoyalDocument.PowerShell.dll' CategoryInfo : NotSpecified: (:) [Import-Module], BadImageFormatException FullyQualifiedErrorId : System.BadImageFormatException,Microsoft.PowerShell.Commands.ImportModuleCommand

Reason

PowerShell by default is built against the .NET framework 2.0 internally. You can check this with the PowerShell variable:  

$PSVersionTable

(look for CLR Version)

Solution

You should update to at least PowerShell 4 - it is included in the Windows Management Framework 4.0. More details can be found at

After installing, you have a newer PowerShell that was built against .NET 4.
