All versions of Measurement Studio released to date include support for Visual C++ 6.0 (and Visual Basic 6.0).
This support is on a separate CD from the support for Visual Studio 2003 and Visual Studio 2005.
For example, the Measurement Studio 8.0.1 kit includes 5 CDs. One CD includes support for Visual Studio 2003 and 2005. Another CD includes support for Visual Studio 6. The other 3 CDs are Device Driver CDs.
You want to use the CD that includes support for Visual Studio 6.0. This CD contains 2 installers. First run Setup.exe. Then run MeasurementStudio6Updater.exe to get the latest components. See UpdaterReadme.htm for information on what components are updated by MeasurementStudio6Updater.exe.
