The VTSX subdirectory within the VTS installation directory (i.e. "C:\VTS\VTSX") contains the ActiveX component that is downloaded by VICs when they connect to a VTS/IS while browsing VTS applications over the World Wide Web. The VTSX subdirectory will only be present if you have purchased a VTS/IS license. Information on this ActiveX component and browsing VTS applications on the web can be found in "VTS Developer's Guide: Browsing VTS Applications on the Web".
