%TOC%

---++ Installation

The ADO.NET Provider for Virtuoso is provided as part of the Virtuoso Client Connectivity Kit installer.  If the target Virtuoso Server installation is already or will be installed on a TCP/IP-accessible host, this is the only component that needs to be installed on the client host.

   1 Download and run the Virtuoso Client Connectivity Kit installer appropriate to your data consuming application from the [[http://virtuoso.openlinksw.com/download/][Virtuoso Download]] page. %BR%%BR% <i><b>Note:</b> the 32-bit components may be installed on both 32-bit and 64-bit Windows, and will be necessary for use with any 32-bit data consuming components.  64-bit components can only be installed in a 64-bit Windows environment.</i>
