Information from how and where to Put Action Files in I found installing the Powershell Right Click tools and then deleting folders by folders. But Having Looked a bit more I might have found this http://eddiejackson.net/wp/?p=16094 Which would have saved me a lot of time.

I suggest that you use the MSI to install this. So The Files that Are called by the Extentions are going to C:\Program Files (x86)\MB_tools\RealVNC_SCCMRightClickTool

The XML Actions Extentions will go to : C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\XmlStorage\Extensions\Actions\3fd01cd1-9e01-461e-92cd-94866b8d1f39

C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\XmlStorage\Extensions\Actions\ed9dee86-eadd-4ac8-82a1-7234a4646e62

Content of the XML File

<ActionDescription Class="Executable" DisplayName="VNC Connection" MnemonicDisplayName="VNC Connection" Description="Created by Maxime Bilodeau">
		<ShowOn>
			<string>ContextMenu</string>
		</ShowOn>

		</Executable>
</ActionDescription>

Also, Disclaimer, If i'm using any Icon that I should not use, please tell me, I can remove it or add a reference if you want. This is 100% a free project that I did mainly for myself and tought that I would Share. Thanks
