OPC Core Components Redistributable (x86)

The Core Components Redistributables installer will install everything that a developer needs (e.g. headers, assemblies outside of the GAC, etc) provided Visual Studio 2005 or later is installed on the machine.

The Core Components SDK will install the same files but will not check for Visual Studio. Developers who wish to use the x64 cross compilers on x86 machines must install the SDK (the x64 headers are not installed by the x86 version of the Redistributables installer).
