Any client workstation may download an ActiveX component from a VTS Internet Server thereby turning a PC without VTS into a VIC (VTS Internet Client).

VTS/IS and VICs are subject to the following licensing restrictions:

•    The server is enabled only on a computer with either a full development or runtime VTS license

•    The number of concurrent VTS Internet Connections you can make to a server is subject to your VTS license. Depending on the licensing options you purchased with VTS, you might have the privilege of connecting from zero to unlimited VIC workstations to your server.

•    Licenses are managed based on a cluster of configured servers. For example, if one server in the cluster is licensed for 5 connections and another is licensed for 10, you will always have 15 available connections.  If the 10-license server goes offline temporarily, your available license count will not drop to the remaining 5 but will remain at 15 on the server that is still running. No existing connections will be lost. For complete details, see: VTS/IS License Clusters.

If you are not sure how many VIC licenses you have available, you can find this information in the About VTS dialog (see Accessing the VTS Version Information.)

Licenses in use are counted on the basis of concurrent sessions, regardless of whether these are run from one computer or from many computers. Each connection to the VTS Internet Server counts as one license in use. If, for example, on a VIC, you opened two tabs in Internet Explorer (tabbed browsing) and then created a connection to your VTS Internet Server from each tab, then that would count as two licenses in use.

An exception is that for support purposes, certain Trihedral-supplied debugging tools (such as the "Debugger", "Profiler", etc.) can always be run, even if their use would exceed the license allocation. Information on the VTS debugging tools can be found in the "VTS Programmer's Guide: Debugging and Analysis Utilities".
