EDIT: It appears to be functional on WM 6.5. You will get an error message about MSVC not appearing to be a valid link, but after closing the message, it will operate correctly. After installation, it will appear in Start --> Settings --> System -->StartUp Manager. (The icon looks like a key in a lock.) To change the settings for a specific item, click and hold down on the application, and select the option from the menu that appears.
