The NI MSDT Redistributables are a set of several underlying build tools that Microsoft allows NI to redistribute. These tools are used to embed compiled resources in user programs and embed type libraries in DLLs. Embedding this information allows ADEs such as TestStand, LabWindows/CVI, and LabVIEW to automatically discover the programmatic interfaces of those DLLs.
You must install NI LabWindows/CVI, NI TestStand, NI LabVIEW, or NI LabVIEW Communications System Design Suite before you can install the NI MSDT Redistributables - Build Tools 8.1.
