Open Rails records in the Window Registry the location of content folders. The registry key is HKEY_CURRENT_USER\Software\OpenRails\ORTS\Folders
There can be one or more values with the registry name set to the name of the installation profile and registry data set to the path of the folder containing ROUTES and TRAINS.
To change installation profiles in Open Rails click the Options button on the main window and click the Content tab in the Options dialog.
