Prerequisites

You must run the programs you create with the Historian User API on a machine with the following software installed and configured:

Historian 5.5 or greater
Historian 5.5 or greater Client Tools

The Historian User API has been tested with Visual Studio .NET 2003, 2005, and 2008.

The Historian User API has no additional hardware requirements.

Historian allows you to develop both 32-bit and 64-bit User API programs.

Note: To build a 32-bit User API program on a 64-bit operating system, you must rename ihuapi32.lib to ihuapi.lib and include it in your program.
