You can install the .NET class libraries (UI, analysis, datasocket,etc.). You can not install C++ support or any integration support. This is not a brain dead installer it is a smart installer because those tools will not work inside the yet to be unreleased VS .NET 2005. The integration needs to be signed by Microsoft for the newer product and installed into the newer product correctly or else you would never be able to use the tools and they would crash Visual Studio.
Try deselecting anything that states "C++" (MFC 7.1 which will not work with Visual C++ 2005) and "integration" in the features listed. This should allow you to install the assemblies. You will have to browse for each cless when "Adding a Reference" because we will not be integrated into Visu
al Studio 2005. This is by Microsoft's design and not ours, that is how we are able to integrate into the compiler.
