When trying to open a runtime that was installed using Vision Client Launcher I get the following error;

Error launching application.  
FileAlreadyExistsException.

The Vision Client Launcher was received via email.

Problem solved.  
I uninstalled the Client Launcher and its folder then reinstalled.  
Works fine now.
